6.2 Cleaning 
The keyfob may get dirty if touched with greasy fingers. Clean it only with a soft cloth or sponge moistened 
lightly with a mixture of water and mild detergent, and wipe it dry immediately. 
The use of abrasives of any kind is strictly forbidden. Also never use solvents such as kerosene, 
acetone or thinner. 
7. TESTING A NEW UNIT 
Since the KF-234 PG2 is supplied with the battery already installed, the unit is practically ready to be tested. 
A. Stand 3 m (10 ft) away from a target control panel (or wireless control panel) and press the ARM AWAY 
button (see Fig. 2). Verify that the red LED lights upon transmission and that the green LED lights upon 
acknowledgement from the PowerMaster-10. 
B.  Make sure that the control panel responds as programmed and as stated in the control panel’s instruction 
manual. 
8. MISCELLANEOUS COMMENTS 
8.1 Product Limitations 
Visonic Ltd. wireless systems are very reliable and are tested to high standards. However, due to their low 
transmitting power and limited range (required by FCC and other regulatory authorities), there are some 
limitations to be considered: 
A.  Control panels may be blocked by radio signals occurring on or near their operating frequencies, regardless of the 
code selected. 
B.  Wireless equipment should be tested regularly to determine whether there are sources of interference and to 
protect against faults.
