First, you will need to determine how much power your radio requires. A radio that is always on, but only listening, will use a minimum of power while idling in receive mode. However, the moment the Push-To-Talk (PTT) is pressed, the power needed to transmit will spike considerably. How much? That depends on several factors, not the least of which is the transmit power level set or programmed into the radio for a particular band or frequency.
1 USER MANUAL TAD M10 We at TAD Radio of Canada Inc., a distributor and designer of professional two-way radios, thank you for using the M10. We are confident that you will be pleased with the M10 -VHF and it will provide you with dependable, trouble-free communications. INTRODUCTION IMPORTANT Please read all the instructions thoroughly before operating the unit. The M10 is capable of 396 channels. This is achieved by 4-groups of 99 channels each. Your dealer has the option of designating different frequencies in each group of the radio for you. This is like having 4 radios in 1. The M10 covers MHz without having to be retuned. It has an alphanumeric display for the channel numbers, channel names, and channel frequencies. The display can be dimmed if necessary, and the display buttons have been backlighted for easier viewing. Its new compact size and lighter weight make installing the M10 quicker. For information on the M10 functions, please read the following pages. The following is a list of items which can be programmed by your Dealer. General Radio features: -1,2, or 4 Banks of 99 channels each plus operating options within each Bank. -Enable Theft Protection by installing a lock number. Each Bank may be programmed with: -TX Time out Timer(30 to 300 seceonds). -How the Priority channel reacts when coming off hook. -Beeps turned off. Each Channel may have: -A Receive(RX) and a Transmit(TX) frequency from 138 to 174 MHz. -A RX and a TX subaudible tone - CTCSS or DCS(Digital Coded Squelch). -A Busy Channel Lockout in conjunction with the channel tone. -A Channel name. This can be an ALPHA name or a NUMERIC number. -TX RF power at a HIGH or a LOW setting. (Usually 30 watts or 10 watts).
2 M10 Radio Controls PWR/VOL- SQL- SCAN - DISP. - PRI.- PRG.- Power and volume control Squelch noise control Channel Scan Display control Priority scan User program control Each of these controls is described in the following section. PWR/VOL Control The radio is turned on and off by pushing this control (Push on, push off.) The audio level from the speaker increases as this control is rotated clockwise. SQL Control This controls the receiver silencing circuitry. To correctly utilize this control, first select an unused channel, then rotate it counterclockwise until noise is heard in the speaker and the BUSY indicator shows in the display. Now rotate the control clockwise until the noise is squelched and the BUSY indicator goes out on the display. This is the most sensitive setting for this control. Rotating this control further clockwise decreases the sensitivity of the receiver. This is sometimes handy in noisy conditions. Channel selector knob Use this control to select a channel. Panel Buttons The four front panel buttons perform two functions each. The first one is performed when the button is pressed and then released after the first beep. The second function is performed when the button is pressed and held in for 2~3 seconds and a second beep is heard. 1 -When the panel button is pressed and released after the first beep : The SCAN button toggles the radio in and out of the scan mode. The SCAN indicator, on the display, will be on when in the scan mode. The DISP button changes the display from channel number, an alphanumeric name (up to 7 characters), to frequency, to tone frequency, then back to channel number only. The PRI button toggles the radio in and out of the priority mode. The PRI indicator, on the display, will be on when in the priority mode. The Priority channel may be selected in the User Programming Mode. If no priority channel has been selected a double beep will be heard and the indicator will not come on.
3 The PRG button puts the radio into the User Programming Mode. The U PROG indicator, on the display, will be on when in the user programming mode. 2- When the panel button is pressed and held until the second beep : The SCAN (A/D) button adds or deletes the present channel from the scan sequence. The D indicator is turned on when the channel is deleted from the scan sequence. (The channel will not be scanned if it is deleted from the scan sequence). When adding or deleting channels, it is recommended that you be out of the SCAN Mode, thus viewing all the channels in the Group. The DISP (DIM) button toggles the display backlighting between dim and normal. The PRI (L/N) button toggles the receiver between normal and low sensitivity. (The LOW indicator is on when the receiver is least sensitive. This is useful in areas where very strong interfering signals are present.the receiver is reset to the Normal condition everytime the radio is turned off.) The PRG button provides access to further programming by an authorized person. (Dealer) MIC connector This is used to connect the microphone to the radio. Cloning Plug Used to connect to another M10 radio,or to a PC, to clone information. or program the radio.
4 INDICATORS GROUP LOW MON PRI SCAN BUSY D D PROG U PROG AUX HORN TONE Active when a group of scanned channels have been selected. A number above will indicate which group is active. Only valid in radios with Group Scan Software. During RX operation this indicates the receiver is operating in reduced sensitivity mode to prevent strong signals from overloading the receiver. During TX operation this indicates low power has been programmed into the TX of this channel. This will only appear when a tone has been programmed into the RX. MON will indicate that the muting function of the tone has been disabled. This may happen when the mic is taken off hook or by enabling the monitor function. On when the priority function has been activated. On when the radio is in scan mode. The radio also requires the mic to be on hook and channels programmed into the scan sequence. Indicates a received signal has exceeded the squelch threshold. Audio will be heard unless a tone is also muting the channel. Appears on all channels NOT in the scan sequence. Radio is operating in Dealer Programming Mode. Radio is operating in User Programming Mode. Not used. On when the external horn blowing function has been activated. (MTS versions.) Active when a CTCSS or DCS tone has been programmed into the channel. RX and TX tones are indicated independently.
5 RX TX Used only during Dealer programming. Appears when the radio is transmitting. SCAN MODE When the SCAN indicator is on the radio will scan all the channels that have been entered into the scan sequence whenever the microphone is hung up. When the radio comes to a channel that is busy it will stop and stay on that channel for the duration of the scan resume time that has been programmed in the User Programming mode or until the channel becomes clear. If a tone is programmed into the RX, it must be valid as well, unless the Monitor function is on. PRIORITY MODE When the PRI indicator is on the radio will continually sample the status of the priority channel. If the priority channel becomes busy the radio will beep and stay on the priority channel until it becomes clear. Pr plus the priority channel number will be displayed on the display. If the mic is taken off hook, one of the following will happen, depending on how your dealer has set the priority option. 1) The radio will always revert to the PRI channel. 2) The radio will revert to the priority channel only if the radio is not on a busy channel. If the radio is on a busy channel, when the mic comes off hook the radio will stay on that busy channel until the mic is placed back on hook. USER PROGRAMMING MODE The User Programming contains four separate modes. Please Note: Bank: 1, 2, 3, or 4. i) Bank number select.(if available) ii) Priority channel select. iii) Monitor on/off select. iv) Scan delay select. a) To enter User Programming press the PRG button. b) Once in the User Programming mode, use the PRI button to select the desired mode. c) In the Priority channel select and the Bank number select mode, use the Channel knob to select a channel or a bank number. In any of the other three modes use the DISP button to select the proper function. The BANK mode in User Programming lets the user select up to four different BANKS of frequencies depending on how the dealer has set up the radio. This means that there can be up to, 4 times 99, or 396 channels installed in the radio. If there are no frequencies installed in a bank it will display CH ALL CLR.
6 Priority Channel May be any valid channel. Monitor on/off Monitor ON = defeats tone muting while on hook unless Busy Channel Lockout has been enabled on the channel. MON indicator is visible on the display when the function is active. Scan Delay :0, 3, 6, or C. 0 = No delay, the radio will resume scanning as soon as the channel clears. 3 = 3 seconds delay, the radio will resume scanning after 3 seconds. 6 = 6 seconds delay, the radio will resume scanning after 6 seconds. C = The radio will resume scanning 3 seconds after the channel has cleared. NOTE: Each BANK is separate from the others so you cannot scan channels that are in another BANK. However, you can have separate Scanned channels, Priority channel and Scan resume times, etc. for each BANK. Channel Revert Active when the radio is in the scan mode (the radio is scanning) If the radio is scanning and not on a busy channel, when the USER takes the microphone Off Hook, the radio will REVERT to the channel that was selected when the scan key was pressed to enter the scan mode. (This channel does not have to be one of the scanned channels.) However, if the radio hears a signal and stops on a channel and the USER takes the microphone Off Hook before the radio resumes scanning, the radio will stay on that channel. M10 DISPLAY MESSAGES Indicates there are no frequencies programmed into this Bank. The radio s PLL is out of lock, on the present channel. If RX is active, no TX is permitted. If TX is active the radio will beep and return to RX when the PTT is released. Radio requires service. 2b1af7f3a8
