Before performing the following steps, refer to Paragraph 2-2 for the location and functional

1. Make sure the transceiver set is connected for operation according
to the installation
instructions in Section 3.
2. Turn on the transceiver by turning the VOL control clockwise.
3. Set the VOL control for the desired volume (the SQ control must be in maximum counter
clockwise position). To hear audio from the loudspeaker the speaker must be enabled
per Paragraph 2-3.1.4.
