3.5.
MODE SELECT
1.
Familiarise yourself with all warnings given at the start of Section 3 OPERATION.
2.
If not already loosened, 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 PCB 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 PCB ENDCAP to reveal the
PCB assembly and switch as shown in the figure below.
5.
Set the MODE SWITCH to the desired position. The switch can be set to either RATE 1
(switch in upper position or PULS on older units) or RATE 2 (switch in lower position or
CONT on older units). Refer to the cover of this manual for the rates available from the
transmitter being used.
6.
Examine the O-ring seals for any signs of contamination or damage, replace and/or re-
grease if necessary.
7.
Replace the PCB 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.
8.
Tighten the M5 grub screw (until the grub screw engages with the housing to lock the PCB
ENDCAP). Note that very little torque is required. Damage may occur if over tightened.
9.
Fully tighten the bleed screw to turn on the transmitter. Use an EM receiver system to
confirm transmitter function and correct transmission rate.
10.
If the transmitter is not to be used immediately after the mode has been selected, 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.
