[. . . ] The transceiver will perform best if the microphone is 5 to 10 cm (2 to 4 in) away from the lips and the transceiver is vertical. SAVE THIS INSTRUCTION MANUAL--This instruction manual contains important operating instructions for the IC-T22A-E. EXPLICIT DEFINITIONS The explicit definitions below apply to this instruction manual. DEFINITION Personal injury, fire hazard or electric RWARNING shock may occur. CAUTION NOTE Equipment damage may occur. No risk of personal injury, fire or electric shock. Versions of the IC-T22A-E which display the "CE" symbol on the serial number seal, comply with the ETSI specification prETS300 684 (EMC product standard for Commercially Available Amateur Radio Equipment). RWARNING! [. . . ] 26) When setting items from memory mode, input data will disappear when changing memories or turning power OFF. Please select VFO mode before entering set mode, and read the instructions for each set mode item carefully. To turn set mode ON and OFF: Push [A V] or [ (CALL)]* for 1 sec. Push [t] one or more times to select the item. Push the [Y/Z] keys to select the desired value. Push [A V] or [ (CALL)]* to exit set mode. I Setting tuning steps USING SET MODE The transceiver has 8 tuning steps as follows: 5 kHz 10 kHz 12. 5 kHz 15 kHz 20 kHz 25 kHz 30 kHz 50 kHz Push [A V] or [f(CALL)]* for 1 sec. Push [t] one or more times to select the tuning step item. Push the [Y/Z] keys to select the desired tuning step. Push the same key used in step above to enter the tuning step and exit set mode. This display shows that a tuning step of 25 kHz is selected. f f For convenience, select a tuning step that matches the frequency intervals of repeaters in your area. *NOTE: Selecting a tuning step is possible using one of the programmable key/switches when this function is assigned using key customize mode (p. In this case, pushing [ (tS)] enters tuning step mode. f When pushing [ ] to exit set mode, any changes made while in set mode are cancelled. 14 REPEATER OPERATION I General When using a repeater, the transmit frequency is shifted from the receive frequency by the offset frequency. Offset frequency of · Selectable steps are the same as the 0. 60 MHz is selected. pre-set tuning steps. Push [A V] to enter the selected offset frequency and exit set mode. When set mode is selected from memory mode: Push [B M]. Push [B M] for 1 sec.

The offset and repeater tone frequencies are not changed by the auto repeater function, reset these frequencies, if necessary. Frequency range and offset direction FREQUENCY RANGE 145. 200­145. 495 MHz 146. 610­146. 995 MHz 147. 000­147. 395 MHz DUPLEX DIRECTION "­DUP" appears "DUP" appears While pushing [8] + [0], turn power on to enter initial set mode. Push [t] one or more times until "AR" appears. Push [Y]/[Z] to select the desired condition. · "oFF"--the auto repeater function is turned off; "on1"--the auto repeater function activates for duplex only; "on2"--the auto repeater function activates for duplex and tone. MR Turn power off, then on again to exit initial set mode. 17 5 REPEATER OPERATION WEATHER CHANNELS (USA version only) There are 10 weather channels for monitoring weather channels from the NOAA (National Oceanographic and Atmospheric Administration) broadcasts. NOTE: The weather channel frequencies are out of the guaranteed frequency range (see p. Intermittent reception and/or poor signal quality may occur depending on conditions. Enter key customize mode (p. 31) and assign the weather function to one of the keys, if necessary. Push [f(WX)] to select weather channel mode. · "WX" and the weather channel number appear. Push [Y]/[Z] to select the desired weather channel. NOTE: Weather channels appear in frequency indication mode only. 18 MEMORY/CALL PROGRAMMING I General The transceiver has 40 memory channels (plus 1 pair of scan edge channels and 1 call channel) for storage of often-used frequencies. In addition, the USA version has 10 marine weather channels (however, these are not programmable). 6 I Programming a memory channel Push [A V] to select VFO mode, if necessary. D Memory/call channel contents The following information can be programmed into memory/call channels: · Operating frequency · Duplex direction (DUP or ­DUP) with an offset frequency (pgs.
