Routine maintenance
This product is designed and manufactured for use in harsh environments and does not require any
specialised maintenance routine program. However, it is recommended to carry out routine
preventative maintenance on this product to ensure that it is kept in good working condition.
Warning! RISK TO PERSONAL SAFETY.
If any part of the radio is damaged, fit new parts to ensure that the radio
operates correctly and maintains its safety compliance ratings. If you are not
certain whether the damage to your radio will invalidate the radio's safety
compliance ratings and product warranty, contact your service provider or
Sepura.
External surfaces
Periodic visual inspections of the product are recommended to check for any damage or wear to
external parts, including penetrating scratches. Some accidental damage may not be covered by the
product warranty and may affect the product’s safety compliance ratings.
Maintenance checks
Perform the following checks:
It is important to check the casing for any penetrating scratches or cracks. Penetrating
scratches or cracks will invalidate the safety compliance ratings of the product. Surface
scratches, those that do not penetrate the casing, are unlikely to affect the operation or
compliance ratings of the product. Cosmetic and physical damage may be prevented by using
a protective case (see
Optional Accessories on page 24).
Ensure that all the keys on the keypad, connectors, buttons and knobs function correctly and
are in good working condition.
On the back of the radio ensure that a bung (12) is fitted to the External Antenna Connector.
The bung is often removed when the radio is used with a car kit that has an external antenna
connection. If the radio is not used with a car kit, replace the bung (12). Radios used without
the bung may gather dust and debris which could affect the operation of the radio.
On the back of the radio, check that the six screws on the rear casing are fitted and secure.
Replace any missing screws and washers. Use an appropriate tool (Torx T6 screwdriver) to
tighten each screw to a torque of 0.35Nm. DO NOT remove or damage the anti-tamper label.
If the label is damaged the product warranty will become invalid.
Antenna
The radio must be fitted with an antenna at all times during operational periods. Transmitting without
an antenna may damage the radio.
If the antenna is removed from the radio for a period of storage, it is recommended that a dust cover
(part no. 700-00790) is fitted to protect the antenna connector.
