[. . . ] During mobile operation, D O N O T operate the transceiver without running the vehicle's engine. When transceiver power is ON and your vehicle's engine is OFF, the vehicle's battery will soon become exhausted. This will avoid possible damage to the transceiver by ignition voltage spikes. During maritime mobile operation, keep the transceiver and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications. [. . . ] 26; meter function) T h r o u g h i n h i b i t (HF bands only) The AT-180 has a through inhibit condition. When selecting this condition, the tuner can be used at poor SWR's. In this case, automatic tuning in the HF bands activates only when exceeding SWR 3:1. Therefore, manual tuning is necessary each time you change the frequency. Although termed "through inhibit, " the tuner will be "through" if the SWR is higher than 3:1 after tuning. CONVENIENT Lights to indicate the AT-180 is turned ON. · For the 50 MHz band: Push and hold [TUNER] to tune the antenna. If the [TUNER] light flashes slowly while transmitting, push and hold [TUNER] again to re-tune the antenna. [TUNER/CALL] · T u n e r s e n s i t i v e c o n d i t i o n (HF bands only) If you require critical tuning at any time during transmission, select the tuner sensitive condition. · A u t o m a t i c t u n e r s t a r t (HF bands only) If you want to turn OFF the tuner under conditions of VSWR 1. 5:1 or less, use "automatic tuner on" and turn the tuner OFF. 54 for turning the function ON and OFF.

AH-4 setting example: For mobile operation Optional AH-2b antenna element AH-4 operation Tuning is required for each frequency. B e s u r e to re-tune the antenna before transmitting when you change the frequency--even slightly. Set the desired frequency in an HF band. · The AH-4 will not operate on frequencies outside of ham bands. USB Push and hold [TUNER] for 2 sec.

CONVENIENT Each memory channel can store a tone frequency and an offset frequency, as well as the operating frequency. Store repeater information into memory channels for quick and easy access to repeaters. · The duplex offset can be selected from ­4000 kHz to +4000 kHz. 17 DUP 144M 30 4 RECEIVE AND TRANSMIT I Tone squelch operation Tone squelch operation is a method of communications using selective calling. Before communicating using tone squelch, all members of your party must agree on the tone squelch frequency to use.
