800 / 1900 MHZ DUAL BAND LINEAR RF COMPENSATOR

MODEL # SYN9528A

USER MANUAL

1. GENERAL

The 800 / 1900 MHz Dual Band Linear RF Compensator model # SYN9528A is a bi-directional,
dual band RF amplifier used in conjunction with either a dual band or a standard single band
mobile phone. It’s designed to compensate for signal attenuation in both transmit and receive
paths due to antenna and cable losses employed in automotive OEM installations. This helps
improving call quality in weak coverage areas and reduce dropped calls in between cell sites. The
compensator operates in both analog (AMPS) and digital (CDMA, GSM, TDMA) modes.

2. INSTALLATION

To meet the FCC’s and IC’s RF Exposure Guidelines, the antenna should be installed so there is
at least 20 cm of separation between the body of the user or nearby persons and the antenna.

WARNING

All installations are done at the factory. No end-user installation or accessible part is involved.
Any unauthorized changes or modifications not expressly approved by the party responsible for
compliance could void user’s authority to operate this equipment.

3. I/O CONNECTION

PORTABLE and ANTENNA port: FAKRA RF type connectors.

DC input and ON/OFF control: 4-pin automotive connector.
