Examine all surfaces for signs of corrosion, scoring and other damage. If there is excessive
damage the mechanical parts may need to be replaced.

Lightly grease all sealing surfaces using a suitable grease (e.g. DOW CORNING MOLYKOTE
111 COMPOUND).
8.
Lightly grease each O-ring with a suitable grease (e.g. DOW CORNING MOLYKOTE 111
COMPOUND) before fitting.

Referring to Section 3.8 BATTERY REPLACEMENT re-insert the batteries and the battery
disc, then refit the BATTERY ENDCAP to the BATTERY end of the housing and the PCB
ENDCAP to the PCB end of the housing using the ENDCAP REMOVAL TOOL. Do not use a
vice or spanner, the endcaps only need to be hand tight.
10.
Tighten the M5 grub screw on each ENDCAP (until the grub screw engages with the
housing to lock each endcap in place). Note that very little torque is required. Damage
may occur if over tightened.

Examine the bleedscrew spring pin for any signs of damage, ensure it is not stuck and has
a smooth travel of approximately 3mm. Fully tighten the bleed screw then loosen 3 full
turns to ensure the transmitter is turned off and use some tape to hold the bleed screw in
this position and prevent it being lost or the transmitter being accidentally turned back on.

ROUTINE MAINTENANCE AND STORAGE
All Online Electronics Ltd transmitters are designed to require minimum maintenance. The
housing should be cleaned using fresh water and cleaning agents as necessary (e.g. WD40).
Do not use chemicals which could be damaging to the housing or ‘O-rings.
Check flame paths / threads on the enclosure body and lid for signs of corrosion or damage. If
badly pitted or damaged, replace the relevant component.
All components that are replaced must be in accordance with the manufacturers’ specifications.
Failure to use such components may invalidate the certification/approval and may make the
equipment dangerous.
Online Electronics Ltd can supply redress kits containing a complete set of replacement
batteries, battery discs, O-rings, O-ring grease, and endcap locking screws, contact Online
Electronics Ltd for more information.
If the transmitter is to be placed in storage for a long period of time remove the batteries and
battery disc from the transmitter and store separately. Refer to Section 3.9 LITHIUM BATTERY
SAFETY for further guidance.
As a minimum the bleed screw must be loosened 3 full turns to switch the transmitter off.
The Transmitter is shipped with a nylon washer underneath the bleed screw to prevent the unit
being accidentally switched on in transit. This washer must be removed before the transmitter
can be turned on.
