The power supply contains voltages that may be lethal. The unit should not be disman-
tled without first disconnecting the mains supply. Servicing should be carried out only
by qualified technicians.

If the power supply is operated at high output currents and/or a high duty cycle rate
for a prolonged period of time (e.g. more than 10 minutes), the heatsink will become
very hot. Do not touch.
Do not operate the power supply in a sealed cabinet. Ensure that there is an adequate
airflow past the unit, and in particular past the heatsink at the back of the unit.

If the mains supply cord needs replacing, it must be replaced with a mains supply cord
of the same size and type as originally fitted.

When using a T2008 and radio at a fixed location, it is advisable to check the maximum
allowable transmit power, as defined by the local radio regulatory authority. This is
commonly in the range of 1 to 5W, and exceeding this output power may result in pros-
ecution.

If the duty cycle (33%) of the radio and power supply is likely to be exceeded, then the
radio output power must be reduced to ensure that the current drawn from the power
supply does not exceed its rating.
It is advisable to check the current drawn from the power supply, regardless of duty
cycle, if the radio is operated at full power (25W). Variations in antenna VSWR can
result in current drain, which may exceed the rating of the supply.
