WARRANTY

A. Ericsson GE Mobile Communications Inc. (hereinafter "Seller") warrants to the original purchaser for use

(hereinafter "Buyer") that Equipment manufactured by Seller shall be free from defects in material, workmanship and

title, and shall conform to its published specifications. With respect to any Equipment not manufactured by Seller

(except for integral parts of Seller's Equipment to which the warranties set forth above shall apply). Seller gives no

warranty, and only the warranty, if any, given by the manufacturer shall apply. Batteries are excluded from this warranty

but are warranted under a separate Nickel-Cadmium Battery Warranty.
B. Seller's obligations set forth in Paragraph C below shall apply only to failures to meet the above warranties (except

as to title) occurring within the following periods of time from date of sale to the Buyer and are conditioned on Buyer's

3. for all other Equipment of Seller's manufacture, one (1) year.

C. If any Equipment fails to meet the foregoing warranties, Seller shall correct the failure at its option (i) by repairing

any defective or damaged part or parts thereof, or (ii) by making available at Seller's factory any necessary repaired or

replacement parts. Any repaired or replacement part furnished hereunder shall be warranted for the remainder of the

warranty period of the Equipment in which it is installed. Where such failure cannot be corrected by Seller's reasonable

efforts, the parties will negotiate an equitable adjustment in price. Labor to perform warranty service wil l be provided at

no change only for the Equipment covered under Paragraph B.3, and only during the first three (3) months following the

date of sale to the Buyer. Thereafter, labor will be charged at prevailing rates. To be eligible for no-charge labor, service

Station or other approved Servicer's place of business will include a charge for transportation. Equipment located off-

shore is not eligible for no-charge labor.
D. Seller's obligations under Paragraph C shall not apply to any Equipment, or part thereof, which (i) has been

modified or otherwise altered other than pursuant to Seller's written instructions or written approval or, (ii) is normally

consumed in operation or, (iii) has a normal life inherently shorter than the warranty periods specified in Paragraph B, or

(iv) is not properly stored, installed, used, maintained or repaired, or, (v) has been subjected to any other kind of misuse

or detrimental exposure, or has been involved in an accident.
E. The preceding paragraphs set forth the exclusive remedies for claims (except as to title) based upon defects in or

nonconformity of the Equipment, whether the claim is in contract, warranty, tort (including negligence), strict liability or

otherwise, and however instituted. Upon the expiration of the warranty period, all such liability shall terminate. The

foregoing warranties are exclusive and in lieu of all other warranties, whether oral, written, expressed, implied or

INTRODUCTION

Figure 1 - Base Station Controls and Indicators

The front panel of the Ericsson GE Desk Top Station, as shown in
Figure 1, includes the front of an MDX conventional/ EDACS™
radio, as well as a Control Panel. The Station is assembled as a
standard Station with or without one of the combinations of options.
The control panel is illustrated for each combination:

•• Standard

Desk Top Station, Without Options - The standard

Station has only a single RED LED to indicate when the power
supply is ON (see Figure 2).

The power supply ON/OFF switch is mounted on the rear of the
Station housing.

OPERATION OF THE STANDARD STATION
WITHOUT OPTIONS

Operation of the Standard Station without any option begins with
turning ON the POWER switch. The POWER switch is located on
the rear of the power supply, accessible at the rear of the Desk Top
Station housing. The POWER indicator lights, showing that the
power supply is ON. The radio is not ON yet. The Power Supply
provides power to the Station cooling fan. The fan operation is
temperature controlled. Internal cabinet temperature determines when
the fan runs. The radio has its own ON/OFF POWER Switch.

The radio uses the Station Speaker mounted behind the front cap of
the Station. The radio's internal speaker is not used. The radio must be
programmed for a variable volume control.

Further operation of the Station is that of the MDX radio. Refer to the
applicable Operator's Manual for more detailed information.

STATION WITH REMOTE OPTION

The DC/Tone Remote Options permit use of ERICSSON GE's RCN­1000 Remote Control Consoles with the Desk Top Station. Any of
these options require that the Station have a DC or Tone Remote
Board with a Remote Interface Board. These options provide for a two
or four wire interface to the consoles for these functions:

• Transmit, Receive and Intercom Audio

• Transmit Keying (PTT) Control

• Channel Guard Monitor

OPERATION OF THE STATION WITH REMOTE
OPTION

Operation of the Desk Top Station is described for four combinations
of the INTERCOM switch and the REMOTE switch positions. These
two switches control the various audio paths between remote and local
microphones, the radio, and remote and local speakers.
