Rechargeable Batteries (4) Boom Microphone/Headset Leather Carrying Case NiMH, P/N GMRS1222BAT GMRSBHST4 GMRS1502LC Powering the transceiver: Your GMRS100 radio transceiver operates on four rechargeable batteries. Only approved rechargeable batteries can be recharged in the GMRS4WM wall mount charger. This will ensure optimum performance for the GMRS100.
Installing the batteries: Battery installation is made more convenient when the carry clip is either rotated left or right to the horizontal position, or is removed. Simply rotate the clip in either direction to the horizontal position. Be careful not to use excessive force. To remove the clip, press down on the spring release tab and pull the clip straight out from the radio body. Next, press down with the thumb at the embossed arrow, slide the battery cover down and lift it away from the compartment.
The following guidelines will improve performance and provide longer operating times for the GMRS100: 1. Do not mix old and new batteries. 2. Do not mix alkaline, standard (carbon-zinc) or rechargeable batteries. 3. If the unit is not to be used for an extended period of time, remove the batteries. Old or leaking batteries can cause damage to the unit and will void the warranty.
GMRS100 OPERATIONAL MODES GMRS/FRS (MODE) CHANNEL SELECT (1-22) CTCSS SELECT (oF, 01-38) POWER SELECT (GMRS channels only) ROGER BEEP (on or oF) NOTE: To differentiate between operating modes, look for HI or LO indication below the battery power level indicator when in GMRS mode.Refer to the appropriate section of this manual for detailed operating instructions for each mode. Channels 1 through 7 are shared GMRS/FRS. Channels 8 through 14 are FRS only, and channels 15 through 22 are GMRS only.
volume. The display will indicate the current volume level (VL) followed by the number (0-7). As volume is increased upward, the unit will beep at each step, and vice-versa. When the minimum and maximum volume settings are reached, a unique tone will sound. Monitor/Display Backlight Button (2) This button is used to to check activity on the current frequency before transmitting.
Up Channel/Volume Button (10) In the standby mode, pressing this button will increment the listening volume. When in function edit mode this button will be used to adjust the unit’s settings. Down Channel/Volume Button (11) In the standby mode, pressing this button will decrement the listening volume. When in function edit mode this button will be used to adjust the unit’s settings. MODE Button (12) This button is used to select various feature settings in the GMRS and FRS modes.
Operating Modes and Features GRMS/FRS Operation: - Press and hold the Power On/Off button for 2 seconds to turn on power. - Press the MODE button so the Channel number flashes. - Select the desired channel with the Up (10) and Down (11) Buttons. When receiving a call, the icon appears to indicate an incoming call. - Press and hold the PTT button (4) to transmit, then speak into the microphone clearly and slowly. The Transmit icon ( ) appears on the display while the button is pressed.
To change the channel: - From GMRS/FRS standby mode, press the MODE button (12) once the channel number flashes. - Press the Up Button (10) briefly to move to the next higher main channel number. - Press the Down Button (11) briefly to move to the next lower main channel number. - Press the PTT button momentarily to confirm selection. CTCSS Mode (Sub-Channel) Selection The Coded Tone Controlled Squelch System (CTCSS) has 38 Sub-Frequencies.
Transmit Power Selection Mode (GMRS Channels Only) This feature permits selection of the transmitting power level to high or low when using channels 1-7 and 15-22. Using low power, the unit will have a lower transmit range, but battery life will be increased. NOTE: You will find that for the majority of your needs, the low-power setting will provide adequate communications on all channels; there should seldom be any need to use high power, except in situations where you need absolute maximum range.
To enable and disable the Roger Beep tone: - From GMRS/FRS standby mode, press the MODE Button 4 times (in FRS mode, 3 times) until the flashing Roger Beep icon ( ) appears with On or oF. - Press the Up or Down Button to select the tone on or off as desired. - When enabled, the tone icon ( ) appears steady on the display. - Press the PTT button momentarily to confirm selection. VOX Selection Mode This option enables you to have hands-free conversation.
Channel Scan Operation This feature allows you to monitor all channels automatically for valid signals. While scanning, you can transmit and receive. When a signal is received, the scan is interrupted and will return to scan mode approximately 5 seconds after reception is terminated. NOTE: While the SCAN mode is active, the MODE button is inoperative. In addition, the scan mode will reduce the overall battery life since the battery save function is overridden.
Battery Alert When the battery icon ( ) blinks steadily on the LCD panel, recharge the unit or install fresh batteries. NOTES FOR GOOD COMMUNICATION 1 . The GMRS100 22 channels are shared on a ‘take turns’ basis. This means other groups may be talking on any of the channels. A common code of ethics/courtesy is to switch to another vacant channel and not to attempt to talk over someone who is already using the channel you first selected. 2.
