5. MAINTENANCE AND INSPECTION
5.1 Daily Maintenance
The life of an equipment like the radiotelephone
largely depends on the quality of maintenance. It is
very important to check the radiotelephone
regularly to keep it in its best condition. Regular
inspection helps to find a symptom of trouble or
prevent trouble before it occurs. It is quite desirable
to perform routine inspection and maintenance
every day according to Table 5-1 below.
