6.6.5 Transceiver Check
6.6.5.1 Instructions
1) If available, use a wattmeter to check the transceiver output power. Refer
to the manufacturer’s documentation for measuring instructions.
2) If available, use two (2) hand-held transceivers and verify the communication
path between the master and remote sites. Voice-activated interface can be
used, if available.
3) Verify that the transceiver is set to the correct frequency. Refer to the
manufacturer’s documentation for checking frequency instructions.
4) If a directional antenna is used, verify the orientation of the antenna to the master
site.
If a communication problem still exists, and the unit has
passed the transceiver check test, contact Totalflow
customer service for additional help.
