OVERVOLTAGE PROTECTION
When exceeding 15.0 volts, the transceiver won’t allow switching to TX mode, (the
voltage indicator on the display will become inverse) a significant excess (more than
16 volts) it can cause the protective fuse to burn out, as well as the failure of the
transceiver! Use a power source or battery with a voltage of 9 to 15 volts and a current
of at least 3 Amps.
A
ATTENTION!
Exceeding the supply voltage above 15 volts can damage
the transceiver!
REVERSE POLARITY PROTECTION
If you connected a minus voltage source or battery instead of a plus, the transceiver
will not turn on. You must connect the external power supply correctly, please, see the
pinout of the power connector in the section “Controls end user interface”.
OVERHEAT PROTECTION
The transceiver has an internal protection against the overheating of the output stage
of the transmitter. If the TX continuous mode is too long, the output stage as well as
the transceiver body can be heated up. If the limit value is exceeded (about 60 degrees
Celsius), the transceiver won’t allow switching to TX mode. After the temperature drops,
the TX prohibition mode will turn off automatically.
A
ATTENTION!
During long-term TX mode (digital modes) do not block the air
access to the rear cover of the transceiver, or reduce the power.
TIP:
Unfold both rear legs to increase the air flow convection.
