Sanitising
Always read the instructions for using the sanitising product carefully and obey all safety instructions
relating to its use.
Regular use of this sanitising product may degrade the hard coat protection of the radio keypad.
To sanitise the radio:
1. Use a damp cloth soaked with a mild detergent to clean the external surfaces. Do NOT use
chemical aerosol or abrasive cleaners.
2. Use a soft brush or cloth to remove any debris from the radio external edges.
3. Dry the radio with a clean lint free cloth.
4. Sanitise the radio using Clinell® universal sanitising wipes.
Allow the radio to dry before operating.
Warning! Do not dry the radio using a microwave oven or with any other
heating device.
Salt water
This radio is designed for use in salt water and salt mist environments. When operating in these
environments the radio must be customised with the Connector Protector feature. This feature
protects the Digital Accessory Connector (sDAC) at the bottom of the radio from corrosive damage
and the feature must be enabled before entering salt water environments. Refer to the product user
guide for more information on this feature.
A cover or an approved accessory must be fitted to the Rugged Accessory Connector (sRAC)
located on the side of the radio, to protect the connector whilst operating in salt water environments.
Salt water is corrosive and may damage the radio. If your radio is exposed to a salt water
environment or you are working in an area with high salt laden humidity, for example when operating
aboard a boat or within the vicinity of the sea in a harbour, using a protective case may reduce the
risk of product damage.
To clean after exposure to salt water:
1. Use a damp cloth soaked with a mild detergent to clean the external surfaces. Do NOT use
chemical aerosol or abrasive cleaners.
2. Dry the radio with a clean lint free cloth.
Allow the radio to dry before operating.
Warning! Do not dry the radio using a microwave oven or with any other
heating device.
