3. MAINTENANCE, TROUBLESHOOTING 

Periodic checks and maintenance are important for maintaining performance. This chapter 

contains maintenance and troubleshooting instructions to be followed to obtain optimum 

performance and the longest possible life of the equipment.   

WARNING

Do not open the equipment.

Only qualified personnel should work inside
the equipment.

 

 

 

3.1 Preventive Maintenance 

General checks 

Check the following monthly. 

 

Check all cabling. If damaged, replace. 

 

Check connections. Retighten if necessary. 

 

Measure the input voltage to be sure it is within the rated voltage (13.6 VDC ±20%). 

 

Cleaning 

Dust or dirt should be removed from exterior surfaces with a soft, dry cloth. Do not use 

chemical-based cleaners to clean the Loud Hailer – they can remove paint and markings.
