Troubleshooting - Quantum Qb1 Compact Operating Instructions

4.7 If the LED "gas gauge" blinks 3 times quickly, see
Troubleshooting - 5.4 Overload Shutdown.
4.8 Two flashes may be powered by QB1c. One flash can use
an "X" series module and the other an "M" series module.
The combined guide number may not exceed 240 (ft) or 72
(meters). This is equivalent to two shoe mount flashes.
Otherwise, we recommend a separate power pack for each
flash,
4.9 Do not exceed the maximum number of full power flashes,
as specified by the flash manufacturer, without a cool-off
period.

5.0 TROUBLESHOOTING

5.1 Flash not powered:
Is the correct Module for your flash connected?
Is the Module in the correct position and firmly seated inside the battery compartment?
Is the Module securely plugged into an output?
Is the Flash switched ON?
Has the QB1c been properly charged?
5.2 Charger not charging:
Is the Charger plugged into a working mains outlet?
Is the Charger securely plugged into the charge input of QB1c?
5.3 Gas gauge LED's are blinking slowly after connecting the charger:
If three LED's blink slowly make sure the proper charger is connected.
If one or two LED's blink slowly QB1c has detected an internal fault. Please return the unit for
service.
5.4 Overload Occurs:
The LED "gas gauge" blinks 3 times quickly to indicate an overload. QB1c power to the module
will automatically shut down. To restart QB1c, determine the cause of the overload and remove it.
Then turn QB1c off and on again.
5.5 Cause of Overload:
A Module inserted incorrectly into a flash battery compartment.
A short circuit across the module contacts. Be sure the contacts do not touch any metal surface.
A defective flash unit which has an internal short circuit (repair or replace flash).
Firing a flash repeatedly before the ready light comes on may result in underexposure and also
stresses the flash.
