INSTRUCTION MANUAL UHF GMRS TRANSCEIVER iF21GM This device complies with Part 15 of the FCC rules. Oper- ation is subject to the following two conditions: (1) This de- vice may not cause harmful interference, and (2) this device must accept any interference received, including in- terference that may cause undesired operation.
i Y our Icom radio generates RF electromagnetic energy during transmit mode. This radio is de- signed for and classified as “Occupational Use Only”, meaning it must be used only during the course of employment by individuals aware of the hazards, and the ways to minimize such hazards.
ii this radio by the manufacturer or an antenna specifically authorized by the manufacturer for use with this radio. • DO NOT transmit for more than 50% of total radio use time ( “ 50% duty cycle”). T ransmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded.
iii Y our Icom F21GM operates on GMRS frequencies (Plus 7 channels shared with FRS ). GENERAL MOBILE RADIO SER VICE (GMRS) GMRS is a two-way personal radio service available to an individual (one man or one woman) to facilitate the activities of the individ - ual's immediate family members.

2 ACCESSORIES 4 ‘ ‘ Accessory attachment D Supplied accessories The transceiver comes supplied with the following accessories. q Flexible antenna w Belt clip D Antenna The antenna screws onto the transceiver as illustrated at right. D Belt clip Attach the belt clip to the transceiver as illustrated below .
5 3 BA TTER Y P ACKS ‘ ‘ Battery pack replacement Before replacing the battery pack, the volume control MUST be ro- tated fully counterclockwise, until a click is heard, to turn the power OFF . • Push the battery release for- ward, then pull the battery pack upward with the trans- ceiver facing you.
6 3 BA TTERY P ACKS ‘ ‘ Battery cautions • CAUTION! NEVER short the terminals of the battery pack (or charging terminals of the transceiver). Also, current may fl ow into nearby metal objects such as a necklace, so be careful when plac- ing battery packs (or the transceiver) in handbags, etc.
7 3 BA TTERY P ACKS ‘ ‘ Battery charging D Rapid charging with the BC-144+AD-99 The optional BC-144 provides rapid charging of optional battery packs. The following are additionally required: • One AD-99 (depends on version.). • An AC adaptor (may be supplied with the BC-144 depending on version).
8 3 BA TTERY P ACKS D Rapid charging with the BC-144+AD-99 D D Spacer combination. • Be sure to attach the spacer (Spacer B/C) to the adaptor (Spacer A) with the orientation as il- lustrated in the diagram at right. • Attach the spacer (Spacer B/C) to the adap- tor with the orientation of the stamp “” pointing up.
9 3 BA TTERY P ACKS D Rapid charging with the BC-121+AD-94 (#1 1) The optional BC-121 allows up to 6 battery packs to be charged si- multaneously . The following are additionally required. • Six AD-94 (#1 1) (Some versions require additional AD-99s).
10 3 BA TTERY P ACKS ‘ ‘ Charging NOTE Prior to using the transceiver for the fi rst time, the battery pack must be fully charged for optimum life and operation. • Recommended temperature range for charging: +10 ° C to +40 ° C (50 ° F to 140 ° F).
‘ ‘ Battery case (Option) When using a BP-208 OPTIONAL BA TTERY CASE attached to the transceiver , install 6 AA (R6) size alkaline batteries as illustrated below . NOTE: Output power is automatically reduced to 1 W to retain suf fi - cient power in case of an emergency , etc.
12 4 SET MODE ‘ ‘ Set mode Set mode is used for programming infrequently changed values or conditions of functions. • All settings performed with [CH selector], [OFF/VOL], [MONI], [PTT] and [W/N] keys. D D SELECTING RF OUTPUT POWER The RF output can be selected from one of 3 modes.
13 2 CHAPTER CONTINUED D D SELECTING RF OUTPUT POWER The transceiver has 3 output power levels to suit your operating re- quirements. Low out put power settings during short-distance com- munications may reduce the possibility of interference to other stations, and will reduce current consumption.

20 5 OPERA TION ‘ ‘ Receiving and transmitting NOTE: T ransmitting without an antenna may damage the trans- ceiver . See p.4 for antenna attachment. T urn power ON as described on p. 2. Program the SIMPLEX/DUPLEX OPERA TION and CTCSS /DTCS tone number (select CH 0 if you will not use the CTCSS function) before operation.
OPERA TION 21 5 D D MONITOR AUDIBLE FUNCTION The monitor function allows you to open the transceiver ’ s squelch manually to check whether a channel is busy or not. The trans- ceiver has 2 conditions for receive standby: Audible condition: This condition mutes audio ONL Y when no carrier is present.
22 5 OPERA TION ‘ ‘ Setting squelch level The squelch circuit mutes the received audio signal depending on the signal strength. Scan proceeds in sequence from lower channel to higher channel numbers. q While pushing [PTT] and [W/N], turn the transceiver ’ s power on to enter the squelch adjustment mode.
23 6 OPTION ‘ ‘ Options D D BA TTERY P ACKS • BP-208 BA TTERY CASE Allows a set of Alkaline batteries to operate the handheld when charging the rechargeable battery or in emergencies, etc. 6 AA (R6) cells are required. • BP-209 Ni-Cd BA TTERY P ACK 7.
24 6 OPTION D D OTHER OPTIONS • HM-46L/HM-75A/HM-131L SPEAKER-MICROPHONES Combination speaker-microphone that provides convenient oper- ation while hanging the transceiver from your belt. HM-75A has programmable function key Mic Up, Mic Down, Mic A, Mic B.
