7-5 Protection Circuit
The Varios 370 has an internal Protection Circuit to prevent overheating. If the internal temperature of the Varios 370
becomes hot, such as when the device is used for more than 10 minutes with the power level set higher than G7, the
output of the device will be reduced automatically to G7. The device will continue to operate at this reduced level until
the internal temperature has reduced to below the protection circuit threshold. During this period, the maximum output
setting that can be used is G8 and to increase output from G7 to G8, output must first be reduced to G5 or lower, then
increased to the maximum of G8. Maximum output can be restored by turning the device off for 15 minutes or longer.
NOTICE • During Protection Circuit function, the Control Unit can not increase the Power Level more
than 8.
