Maintenance
Your Two Way Radio is an electronic product of exact design and should be

• Do not store the Radio under the sunshine or in hot areas.
• High temperatures can shorten the life of electronic devices, and warp or
melt certain plastics.
• Do not store the radio in dusty and dirty areas.
• Keep the Radio dry. Rainwater or damp will corrode electronic circuits.
