operatIon notIceS
The transceiver has been designed and engineered to avoid
possible hardware glitches. However, you may notice the following
symptoms when you operate the transceiver. These symptoms are
not malfunctions.
receIvInG SIGnalS In cItIeS
When you receive signals in cities, the receiver’s entire antenna
indicator may light up without receiving any strong signals. This
happens when the RF amplifier in the receiver is overloaded by
strong interference signals that are nearby.
tranSmISSIon
If you continuously transmit for more than 8 minutes at high power (5
W), the transceiver becomes warm.
If you continue or repeat the transmission before the transceiver
cools down, the thermal protector gradually decreases the output
power down to 1.5 W.
Internal BeatS
On some spots of the frequency, the antenna indicator moves
without receiving any signals or you cannot receive any signals.
This is inevitable when you use super-heterodyne receivers. If this
happens, access Menu No. 17 (BS) and select “ON”.
Internal Beats Frequency
140.800 MHz, 153.600 MHz, 166.400 MHz
