TS22 Amplified Speaker

The TS22 Test Set has an amplified speaker that
amplifies the received signal in TALK or MONITOR
mode. This lets you listen to the test set without
holding it to your ear.
The SPEAKER button controls the volume of the
amplified speaker. The speaker has three volume levels
(low, medium, and high).
When the speaker is on, the polarity LEDs go
out. They will turn back on when the speaker
timer elapses or is turned off via the SPEAKER
button.
When the speaker is on, the transmitter and receiver
are automatically switched off to prevent acoustic
feedback. With no signal present, the speaker will
automatically turn off after 5 minutes to conserve
battery power. Any signal greater than a nominal
-30 dBm will reset the timer and keep the speaker
turned on.
