Push-to-talk button (PTT)

You will find the PTT-button at the side of the microphone. For transmission you push this button for as

long as you want to talk. When you finish talking release the PTT and your radio is automatically ready

for reception again. The correct distance to your microphone is between 4 and 8 cm. Speak with the

same loudness as if you were on the phone. Most of the radio beginners talk too loud into the

microphone! Wait a moment after having pushed the PTT before you start talking: Your transmitter has

to switch from the reception frequency to the transmitting frequency, at your partner`s side the squelch

needs time to open! The delay can be between about 140 mseconds at open squelch and a max. of

300-500 msec when CTCSS coding & decoding is applied. Thus a syllable talked too early or quickly can

be lost!

TONE CALL 1750 Hz

For repeater access most European repeaters request a tone burst 1750 Hz , appr. 1 s long. Transmit

this tone by using the

T-CALL

key at the radio front panel. T-Call is being transmitted as long as the button is being pushed.

Please do not mix up this button with the CALL/T-SQ button at your microphone! This button operates

the CALL-channel described in the next paragraph.

Direct access to „Call“ channel

With the button

CALL/ T-SQ

you switch from your operating channel to a previously determined call channel and back. The

manufacturer preprograms it to 145.500 MHz, the international FM-call frequency of the IARU Region I.

In case you want to store a different frequency for the direct call channel please use the Set-up menu.

Frequency search mode SCAN

By pushing the SCAN button the radio automatically searches for frequencies which are being used by

other transmitters. Before starting this process please adjust squelch correctly, otherwise searching

neither can be started or stopped. Preferably SCAN is being started in VFO-mode, it will then search the

complete band. As soon as SCAN finds an already occupied channel it stops there. You will then hear

the radio traffic on this channel for max. 6 sec. During this time you have the opportunity to either stop

scanning by touching the PTT button or by again pushing the SCAN button.

If no action is taken searching will be continued after the waiting period. Searching can be done on VFO

frequencies or between memory channels depending on the mode the radio is in when searching starts.

Recalling memory-channels MR / MS

The button MR/MS ( Memory Recall / Memory Save) switches directly to the stored channels (Memory

Mode). In case you already have stored frequencies you can select these with the rotary switch. The

small digit will show the memory location number 1-0 or C (flashing on free, unused memory locations

and continuously on when you select a stored memory location.

Microphone lock

To prevent operation by mistake there is a small switch at the microphone that locks all the microphone

buttons except the transmission key. This lock will be activated by turning the sunken slide switch on the

microphone to the right position MIC LOCK ON.

Tone call, VFO and memory buttons of the radio can still be operated.
