Replacing the fuses
The detector requires two 100 to 240 VAC, 50 to 60-Hz, F 3.15-A, 250-V
(fast-blow), 5 × 20 mm (IEC) fuses.
Suspect a fuse is open or otherwise defective when
• the detector fails to power-on.
• the fan does not operate.
To replace the fuses:
Requirement:
Replace both fuses, even when only one is open or otherwise
defective.
1. Power-off the detector and disconnect the power cord from the power
entry module.
2. Pinch the sides of the spring-loaded fuse holder, located above the power
entry module on the rear panel of the detector.
3. With minimum pressure, withdraw the spring-loaded fuse holder.
Warning:
To avoid electric shock, power-off and unplug the 2998
PDA detector before examining the fuses. For continued protection
against fire, replace fuses with those of the same type and rating
only.
