GENERAL
WARNINGS
1. ALTHOUGH THE SOUNDER HAS BEEN DESIGNED FOR RELATIVELY SIMPLE
INSTALLATION, THE COMPLETE PROCESS, INCLUDING FIELD CALIBRATION AND
GAINING ACCESS TO THE INSIDE OF THE SOUNDER, REQUIRES SPECIAL
KNOWLEDGE GAINED BY ATTENDING A TRAINING COURSE AND DEVELOPMENT
OF THE REQUIRED PRACTICAL SKILLS. THEREFORE NO ATTEMPT SHOULD BE
MADE TO INSTALL, CONNECT POWER TO, OR CALIBRATE THE SOUNDER AND
ITS ANCILLARY DEVICES BY UNQUALIFIED PERSONS.
2. WHEN PACKED FOR SHIPMENT THE SOUNDER WEIGHS APPROXIMATELY 60
KGS. THEREFORE AT ALL TIMES AT LEAST TWO PERSONS MUST LIFT AND
CARRY THE EQUIPMENT SAFELY BY THE CASE CARRYING HANDLES.
3. NO AUTHORIZED INSTALLATION, OPERATION OR MAINTENANCE TASK
REQUIRES THE MAIN AND POWER AMPLIFIER CHASSIS TO BE EXTENDED OUT
OF THE CASE AT THE SAME TIME. IF BOTH ARE EXTENDED, THE COMBINED
MASS OF THE TWO CHASSIS, WILL ALTER THE SOUNDER’S CENTER OF
GRAVITY AND WILL CAUSE THE EQUIPMENT TO TOPPLE FORWARD
POTENTIALLY CAUSING INJURY TO PEOPLE AND/OR DAMAGE TO CABLES AND
OTHER EQUIPMENT.
CHAPTER 1
GENERAL SOUNDER CONFIGURATION
2:1. The sounder is provided with a fiberglass field transit case (see Figure 1-1) which is also used to pro-
tect the internal components during normal use. During installation, all external connections to the sounder
are made with both chassis secured in their normal operating position (i.e., closed) and the rear shipping
cover in place. The front cover should normally be left in place during normal operation.
2:2. Under normal operating conditions, the sounder and most of its ancillary equipment, including a moni-
tor and keyboard, shall be installed in a clean, air-conditioned environment. It will normally be placed on a
level table, with no special or fixed mounting requirements being necessary. Desirably, the table shall also
serve as an operator’s and maintainer’s work bench. Its exact position shall be dictated by the proximity to
any antenna through-wall feeders specified by the facility design.
2:3. A single phase double power outlet will be required within approximately 2 m of the table. Where
back-up power is required, an appropriate UPS shall be installed.
2:4. Specifications on the sounder hardware are provided in Section 6 and Annex A of the manual.
