External Speaker; Public Address - Stryker SR-497hpc User Manual

Tuning the Antenna for Optimum SWR
3. The whip is easily cut by filing a notch all the way around,
then breaking the piece off with pliers.
NOTE
The proper setting is achieved when the SWR is 1.5 or below and when it has
the same reading for the low and high frequencies in the range you plan to use.

External Speaker

The external speaker jack (EXT) on the rear panel is used for remote receiver
monitoring. The external speaker should have 8 ohms impedance and be able to
handle at least four watts. When the external speaker is plugged in, the internal
speaker is disabled.

Public Address

To use the transceiver as a public address system, connect an external 8 ohm speaker
that is able to handle at least four watts to the PA jack on the rear panel. Direct the
speaker away from the microphone to prevent acoustic feedback. Physical separation
or isolation of the microphone and speaker is important when operating the PA at high
output levels.
Improper Radio Adjustments
Service by unqualified technicians could result in damage to your radio. Never allow
anyone to disable your radio's modulation limiting circuitry. We have designed your
radio for optimal performance and durability. Disabling this circuitry could damage
your radio and potentially void your factory warranty!
