When the Receiver is used in a non-contact search, it is recommendable to use the telescopic arm
supplied with ST300. This will, firstly, prevent the user’s body capacitance affecting the receiver, and
secondly, make it easier to explore the upper walls and ceiling.
The arm consists of a telescopic handle and bracket-and-clamp assembly. The telescopic arm is shown
in Fig. 6.
Fig.6
The numbers in Fig. 6 represent:
1 - hold-down bar
2 - bracket
3 - cable with a pin connector
4 - screw connecting the bracket to the
telescopic arm
5 - screw that fixes the position (incline) of the
bracket
6 - telescopic handle
To mount the Receiver onto the telescopic arm
and prepare it for operation, pull up the hold-down
bar 1, place the Receiver as shown in Fig. 7 and
release the hold-down bar.
Plug the pin connector 3 into the corresponding
socket of the Main Unit (1, Fig.5).
