If the unit appears to have developed a problem, first establish that it is a genuine internal problem and

not a case of normal operation such as overheating. Carry out the following checks to eliminate any

external causes. If no obvious problem can be found and replacement of the modelling lamp, flash tube

or flash head fuse does not eliminate the problem, then it is likely that an internal problem has

developed. 

Always return the unit to an authorized service centre if a problem is suspected after these

checks. UNDER NO CIRCUMST

The power pack is fitted with a thermostatically controlled fan, but under extreme conditions of use the

power pack may still overheat, even with the fan running. Flashing less frequently and/or using the

Slow Charge Mode will normally help prevent this from happening.

Overheat protection is provided to inhibit charging until the unit has cooled suf

ficiently to operate

normally

The Power Level Displays will flash “Overheat” warning while the overheat condition exists.

NOTE: 

The overheat condition remains until the power pack reaches a safe operating temperature or

the unit is turned of

If the Control Panel does not light up when the unit is switched on, first check the

AC outlet is working. Under exceptional conditions of use or

component failure, the Internal Fuse may blow
