ROUBLESHOOTING
Please check the troubleshooters listed below if you experience a problem with
your unit. Then, if you still are unable to solve the problem, we encourage you
to call Technical Support at (510) 732-7814 for assistance (Mon-Fri, 7am-5:30pm
PST). Please do not return your unit for repair without prior authorization.
✦
The LEDs do not flash on powerup.
Make sure that your power cord connections are secure. If your unit is AC-
powered, try plugging the repeater into another outlet and some other
(functioning) device into the outlet you are using.
If your unit is solar-powered and the gel cell battery is over 5 years old, try
replacing the battery. (Do not incinerate the used battery, it may burst.
Arrange for proper recycling in your locality.)
If your unit is solar-powered and the battery is less than 5 years old, make
sure the panel is not being shaded by the sun. Open the shelter and check
that the wire connections are secure and that the battery is free from corro-
sion and excessive deposits on the terminals. Clean the solar panel using a
water spray, or a soft cloth and soapy water followed by a clean water rinse.
Check the battery’s voltage with a voltmeter; the battery must have at least
3.8 V to power the station. (More than 4 V indicates and adequately-
charged battery.) Try exposing the panel to ample sunlight for a week, or use
a charger designed to recharge a 4 V gel cell battery.
✦
The LEDs do not flash twice after the self-diagnostic.
If you consistently get the first flash upon powerup but no double-flash
7 seconds later, something is wrong with the unit’s circuitry. Please contact
Technical Support for assistance (see above).
✦
The lower LED is not lighting up, but the upper one is.
When the repeater fails to receive a valid data packet, it still sends out a "no
data" packet to keep downstream repeaters in sync. Therefore, even if no
data packet is received, the lower receive LED will not light but the upper
transmit LED will. This is useful in a network situation because it can show
where the last good packet was received in a chain of repeaters.
If the lower LED is consistently failing to light up, make sure the transmitter
(or repeater) that it is listening to is powered up and functioning correctly.
You can also try moving the repeater closer to the transmitter (or prior
repeater) or for better reception.
