PRECAUTIONS
To avoid malfunctions and damages, and to achieve full
performance, please pay careful attention to the following
matters:
1. During transmission, the heat sink may reach a high
temperature (approx. 50°C-80°C). Set the amplifier in a
well- ventilated place. Do not place objects on top of the
amplifier. Do not operate the amp in places exposed to
direct sunlight or close to a heater, etc.
2. If the antenna matching condition is poor (or the SWR is
high), please try to lower the SWR. This is also
important to ensure the efficient transmitting of output
power from the antenna. Also, check make sure the
antenna is properly connected and there is no short or
open before operation.
3. Keep the input power at 5W or less.
4. Be careful that the DC voltage is kept below 13.8V (12
14V). The amplifier could be damaged is connected to a
DC 24V battery (for truck use) or AC power source.
5. Never connect the whip antenna of a handy-transceiver
directly to the antenna connector of the amplifier unit
using M-BNC converting connector etc. It may cause
damage to the antenna due to insufficient power capacity.
It may also damage the transceiver or the amplifier when
strong RF signal intrusions occur.
