12. MAINTENANCE
12.1 Maintenance and warnings
KV-300 is a marine VHF transceiver that conforms to IPX7 standard, making
the transceiver very reliable when used correctly.
The device was designed so as to avoid requiring maintenance. To keep your
transceiver in optimal operating conditions:
Never open the device (transceiver or microphone) as this may compromise
the water resistant seal.
If the device becomes dirty or dusty, do not use alcohol, solvents or abrasives
to clean it. Use only a soft cloth, slightly dampened with water. For more persi-
stent cases, use a mild detergent.
