Caution
Removing a unit
1. Lay the BTS on its back, in the position shown in Figure 4.
2. Loosen the upper and lower retaining screws of the unit to be removed
using a torque driver with a T10 Torx bit.
Loosen the screws enough to remove the unit, but leave them engaged in
the threads. By doing this, the screws remain in the optimal position for
reconnecting.
3. Slide the TRX units out of the slots by pulling from the handle on the front
panel of the TRX.
4. Remove the power supply unit, interface unit, and transmission unit by
pulling each unit out until it comes to a stop. Then lift the unit upwards and
outwards to remove it. See Figure 4.
If the unit does not come out easily, rock it slightly from left to right using the
handle and then pull the unit out. Do not use excessive force!
When handling the units, beware of sharp edges!
