Detailed instructions for use are in the User's Guide.

[. . . ] INSTRUCTION MANUAL iT81A/E MULTIBAND FM TRANSCEIVER This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. IMPORTANT READ ALL INSTRUCTIONS pletely before using the transceiver. NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the body, especially the face or eyes, while transmitting. 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-T81A/E. EXPLICIT DEFINITIONS The explicit definitions below apply to this instruction manual. [. . . ] 10 BASIC OPERATION 4 I Selecting a memory channel Push [MR] to select memory mode. Push [MULTI()] (or rotate [DIAL] or push digit keys) to select the desired memory channel. · Only programmed memory channels can be selected. · Memory channels 1­9 are preceded with a "0" when selecting with the digit keys; push "0@" to select scan edge 0A, push "0 ?" to select scan edge 0B. MR MR I Receive and transmit Push [PWR] for 1 sec. · 10 selections are available, "OPEN, " "AUTO, " and "SQL 1 to "SQL 8. " 9 MR Set an operating band and frequency. 9 MR Push [H/L] to toggle output power between high and low. · "LOW" appears when low output power is selected. · When a signal is received: Squelch opens and audio is emitted from the speaker. The [TX/RX] indicator lights green. Push and hold [PTT] to transmit; then speak into the mic. · Do not hold the microphone too close to your mouth or speak too loudly. · The [TX/RX] indicator lights red. I Lock function Push [(H/L)LOCK] for 1 sec. to toggle the lock function on and off. · "L" appears while the lock function is activated. · [PTT], [PWR], [MULTI()] (volume), [SQL] and [H/L] can be used even when the lock function is activated. Release [PTT] to return to receive. CONVENIENT Monitor function: Push and hold [SQL] to listen to weak signals that do not open the squelch. 11 4 BASIC OPERATION play, then rotate [DIAL] to select a frequency; or, I FM broadcast reception The transceiver can receive FM radio broadcasts. These are typically in the range 76­107. 995 MHz (88­107. 995 for some versions) and are in WFM receive mode. To select the FM broadcast band: W FM Push [MULTI()] one or more times until "WFM" appears in the display, then rotate [DIAL] to select a frequency; or, Select a frequency with the digit keys directly. · "WFM" automatically appears when a frequency in the range 76­107. 995 MHz is input. Select a frequency with the digit keys directly. · "AM" automatically appears when a frequency in the range 118­135. 995 MHz is input. NOTE: When pushing [PTT], "OFF" appears indicating the frequency and mode are outside the permitted range. SET MODE I Narrow FM* operation (Europe, France, Italy ver. ) USING Push [MULTI()] one or more FM NOTE: When pushing [PTT], "OFF" appears indicating the frequency and mode are outside the permitted range. I Air band reception (Asia, USA ver. ) The transceiver can receive frequencies reserved for commercial/private aircraft and ground support. These are in the range 118­135. 995 MHz and are in AM receive mode. Push [MULTI()] one or more times to display "MO, " if necessary. Push [VFO] to exit set mode and return to regular operation. Push [MULTI()] one or more times until "AM" appears in the dis12 *NOTE: FM narrow operation can be set for individual memory channels or in VFO mode; narrow FM affects BASIC OPERATION 4 I RIT/VXO function (1200 MHz band) In the 1200 MHz band, differences between actual and displayed frequencies can often be large. The RIT (receive incremental tuning) function allows you to compensate the displayed frequency for differences in the actual receive frequency; the VXO (variable crystal oscillator) function allows you to compensate the displayed frequency for differences in the actual receive and transmit frequencies. D Adjusting the frequency with RIT/VXO Make sure that RIT or VXO is activated in set mode and that the 1200 MHz band is selected. Select a frequency in the 1200 MHz band (or a memory channel with a 1200 MHz band frequency; or the 1200 MHz band call channel). Push [MULTI()] one or more times (or rotate [DIAL]) to adjust Offset: ­2 kHz (approx. ) the frequency offset. · The frequency offset can be set ±5 kHz in 1 kHz steps. Offset: +5 kHz (approx. ) D Activating RIT/VXO USING SET MODE Select a frequency in the 1200 MHz band (or a memory channel with a 1200 MHz band frequency; or the 1200 MHz band call channel). Push [MULTI()] one or more times to select "RIT" (RIT activated, "VXO" (VXO activated) or "OFF" (neither activated)--[DIAL] can also be used. Push [VFO] to exit set mode and return to the previously selected mode. · When RIT or VXO is activated, ":" appears above the decimal point in the frequency indication (in the 1200 MHz band). NOTE: When using the RIT/VXO function the indicated offset frequencies are only approximate values. 13 4 BASIC OPERATION I Receive mode USING SET MODE The IC-T81A/E allows you to receive frequencies in the 50 MHz band in AM mode (as well as to transmit in FM narrow mode in the 144 MHz band for Italy, France and Europe versions only--see p. Push [MULTI()] one or more times to select the 50 MHz band. Push [MULTI] for 1 sec. [. . . ] 7, (A slight current flows in the circuits even when the teries in the battery case. 8 (Remove the battery pack if you will not be using the transceiver for a long time. ) Transmitting is impossible. · The lock function is activated. · Charge the batteries or place new dry cells in the pgs. 11 · The same frequencies are programmed into XA · Program different frequencies.
