Service manual

FOREWORD
The information contained in this manual relates to all ASTRO Digital SABER radios, unless otherwise
specified.
SAFETY INFORMATION
The Federal Communications Commission (FCC), with its action in General Docket 79-144, March 13, 1985,
has adopted a safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by
FCC-regulated equipment. Motorola subscribes to the same safety standard for the use of its products. Proper
operation of this radio will result in user exposure substantially below FCC recommended limits.
• DO NOT hold the radio with the antenna very close to, or touching, exposed parts of the body, especially the
face, ears, or eyes, while transmitting. Hold the radio in a vertical position with the microphone two to three
inches away from the lips.
• DO NOT hold the transmit switch (PTT) on when not actually desiring to transmit.
• DO NOT allow children to play with any radio equipment containing a transmitter.
• DO NOT operate this equipment near electrical blasting caps or in an explosive
atmosphere. Under certain conditions, radios can interfere with blasting operations.
When you are in the vicinity of construction work, look for, and observe, signs cautioning
against radio transmissions. If radio transmission is prohibited, you must not transmit until
out of the area. Furthermore, you must turn off your radio to prevent any accidental
transmission.
• DO NOT replace or charge batteries in a hazardous atmosphere. Contact sparking may
occur while installing or removing batteries and cause an explosion.
• TURN THE RADIO OFF when removing or installing a battery.
Anyone intending to use a radio in a hazardous area is advised to become familiar with the subject of intrinsic
safety and with Section 70 of the National Fire Code, which is commonly referred to as Article 500 of the National
Electric Code. Use of anything but factory supplied components may affect the approval and safety of the radio.
Likewise, it is advised that servicing should be performed only by qualified personnel who adhere to the following
Factory Mutual (FM) required warning:
