Sepura SC21 Series Service Guide

The Rugged Accessory Connector (sRAC) on the right-side of the radio must be fitted with a cover
assembly (7) when an accessory is not in use.
The radio is manufactured without a cover for the Digital Accessory Connector (sDAC) located at
the base of the radio.
Caution! Take extra care when cleaning the External Antenna Connector.
Applying excessive force may permanently damage the connector.
The External Antenna Connector on the rear of the radio should also be cleaned using the same
procedure, first removing the rubber bung, if fitted. If a mild detergent is used, ensure that the
connector is left to dry completely before placing the radio into a cradle.
Cleaning around the battery compartment
Remove the battery and the smartcard before cleaning the battery compartment.
To clean the battery compartment:
1. Use a soft brush to remove any dust and debris around the battery compartment.
2. Clean the battery contacts using a dry lint free anti-static soft cloth or soft brush.
Warning! Do not use a damp or wet cloth or cleaning fluids on the battery
contacts.
3. Carefully lift the smartcard holder retainer, and using a soft brush remove any dust or debris
from the smartcard holder compartment.
4. Clean the smartcard contacts using a dry lint free anti-static soft cloth or soft brush.
Specialist cleaning
Sometimes the radio may be subjected to conditions that require additional cleaning such as salt
water, mud, body fluids and foul substances such as sewage. If your radio has been subjected to
contamination, seek advice from your local Health and Safety authority.
Warning! PERSONALSAFETY. Always obey your local health and safety
procedures when using potentially harmful cleaning solutions. Appropriate
Personal Protective Equipment (PPE) should be worn when cleaning the
radio.
Contamination
If the radio becomes contaminated, for example with blood or other body waste products, it must be
decontaminated by a ‘specialist decontamination’ company. Sepura does not provide facilities to
decontaminate any of its products.
When the radio has been decontaminated, a Certificate of Decontamination is issued.
Sepura does not accept ANY contaminated products for servicing or disposal WITHOUTbeing
cleaned and decontaminated before shipping. Contaminated products are only accepted for
