BATTERY REPLACEMENT
1.
Familiarise yourself with all of the warnings given at the start of Section 3 OPERATION.
2.
Using a 10mm AF Allen key loosen the bleed screw 3 full turns to release any internal
pressure and to turn the transmitter off. There is no need to fully remove the bleed screw.
If you do so it may be lost.
3.
Using a 2.5mm AF Allen key fully unscrew the M5 locking grub screw on the BATTERY
ENDCAP. The grub screw may be screwed back in 3 turns to prevent it getting lost.
4.
Using the supplied ENDCAP REMOVAL TOOL, fully remove the BATTERY ENDCAP.
5.
Remove all ELECTROCHEM 3B0035-TC Lithium cells and the battery disc. Visually inspect
the batteries, contact Online Electronics Ltd immediately if there are any signs of damage
or electrolyte leakage. Dispose of the old batteries in a responsible way. Refer to section
3.9 LITHIUM BATTERY SAFETY for further guidance. Place the battery disc safely to one
side so it doesn’t get lost.
6.
Observing the battery polarity shown in the figure below, insert 2x new ELECTROCHEM
3B0035-TC Lithium D cells into the battery compartment POSITIVE END first with a 3015X-
031 LIT BATTERY DISC between neighbouring cells. A total of 1x battery disc will be
required.
7.
Once all batteries are installed ensure that it is the FLAT, NEGATIVE END of the batteries
which you see when looking into the open end of the transmitter.
8.
Examine the O-ring seals for any signs of contamination or damage, replace and/or re-
grease if necessary.
9.
Replace the BATTERY ENDCAP using the supplied ENDCAP REMOVAL TOOL. Do not use a
vice or spanner, it only needs to be hand tight. Damage may occur if over tightened.
10.
Tighten the M5 grub screw (until the grub screw engages with the housing to lock the
BATTERY ENDCAP). Note that very little torque is required. Damage may occur if over
tightened.
11.
Fully tighten the bleed screw to turn on the transmitter. Using an EM receiver, confirm
transmitter function and correct transmission rate.
12.
If the transmitter is not to be used immediately after battery replacement, loosen the
bleed screw 3 full turns to switch the transmitter off and use some tape to hold the bleed
screw in this position to prevent it being lost or the transmitter being accidentally turned
back on.
