3) Select the desired upper tuning limit. For example, you might want to select the 145 MHz band and dial up
145.100 MHz.
4) Press and hold the M key for longer than one second, then press the 2 key. This selects the upper frequency
limit for the programmable VFO.
5) To confirm that the programming was properly performed, rotate the Tuning control. The transceiver should
not go above or below the programmed band limits.

Basic Receiving Functions

When receiving a signal, the Main/Sub S-meter deflects and the Main/Sub BUSY indicators appear.
Rotate the volume control to the desired level.
Note
For information about more advanced receiving capabilities, see Enhanced Receiver Function on page 39.

TRANSMITTER OPERATION

WARNING
Before you attempt to transmit, attach an antenna with a low standing wave ratio to the antenna
connector. Failure to provide a proper load may cause damage to the final amplifier section. Always
check that the frequency is clear before transmitting.
1 To transmit, follow these steps:
1) Use any of the frequency selection methods discussed on page 10 to select an operating frequency.
2) Listen to the frequency to see if it's occupied before attempting to transmit on it.
3) Press the PTT (Press to Talk) switch. The ON AIR indicator and battery level meter will appear.
4) Speak into the microphone from the recommended distance of 2 inches. Talking closer or farther away can
result in loss of clarity, an excessively wide transmit signal, or weak audio.
5) Release the PTT switch to return to the receive mode. The ON AIR and battery level meter indicators should
go out.
