4.4 Setting up a signal repeater

You can expand the range of the unit signal by using a second unit. The
second unit will repeat the signal from the primary unit which is installed on
the pump.
The primary unit must be on and transmitting data.
1. Turn on the second unit.
2. Place it between the primary unit and the position with poor signal.
3. Make sure the status indicator light on the second unit is flashing twice
every second. Refer to the table below.
The signal is now being repeated and the range is extended.
