Attachment with clip

With the clip the transmitter can be easily attached to the waistband or belt (Iig. 8). Since the microphones MKE2012 and MKE 4012 are

not suitable lor this kind 01 application a clip-on microphone, e. g. MKE 2 R, MKE 10 R or MKE 40 R should be used instead.

During operating avoid pressing the antenna against your body or winding the microphone cable around it. Otherwise the radiated power would be reduced.

Operation with batteries or rechargeable batteries

The transmitter may be powered either by alkaline battenes, type Mignon IEC LR 6 or by nickel cadmium accumulators (1.2 VI

500 mAh). The prelerred type 01 battery should be the alkaline 'type, as other types 01 dry cells might not ensure reliable operation 01 the transmitter. In Irequent use 01 the transmitter nickel cadmium

accumulators are more economical. These can be recharged with a SZL 1011-2battery charger. The SK 1011leatures two lateral contacts @)lor recharging; so the batteries can remain in the set whlle recharging them. Depending on the type 01 battery used, there are variations in operating time:

NiCd-accumulators: approx. 10 hours

alkaline batteries: approx. 30 hours

Hints for operation on rechargeable batteries

1.Switch off the transmitter belore recharging.

2.Always put the transmitter after use Into the charger. This will ensure that the accumulators are at all times optimally charged.

3.Carelully read and always observe the instructions lor use 01 the battery charger.
