9. Basic Operation
First, install the recommended antenna, turn on the radio, select the channel agreed upon
between stations (surface and underground), and tune the antenna. Adjust the speaker volume as
needed on the receiver.
To make a voice call after the radio is ready, hold down on the PTT then speak into the Smart
Handset microphone. When finished speaking, release the PTT and listen for responses from the
other station using the Smart Handset speaker and/or the built in speaker in the radio.
Ensure that the STR-1000 is always operated within the temperature range of -30 to +60 degrees
C
(-22 to +140 degrees F).
Important Note:
Avoid keeping the radio in an excessively hot vehicle before operation. This
is especially true in the Desert Southwest.
A grounding cable is provided for surface operations where antenna tuning is difficult or
excessive receive static interference may occur. The grounding cable plugs into the Grounding
Connector (see Figure 1 for location) and clipped to a grounding rod (not provided).
