WARNING
FCC Rules require that ALL transmitter adjustments, other than those supplied by the manufacturer as front panel operating controls, be made by or
under the supervision of the holder of an FCC issued I st or 2nd class radio operator's license.
Replacement or substitution of crystals, transistors, regulator diodes or any other part of a unique nature, with parts other than those recommended by
the manufacturer may cause violation of the technical regulations of Part 95 of the FCC Rules or violation of the Type Acceptance requirements of Part
2 of the Rules.
SECTION 2
INSTALLATION & INITIAL ADJUSTMENT
IMPORTANT
BEFORE DISCARDING ANY OF THE PACKING MATERIALS, EXAMINE THEM CAREFULLY FOR ITEMS YOU MAY HAVE
OVERLOOKED.
INSTALLING FIXED STATION
For fixed station operation, connect the AC power cable from the back of the unit to an AC outlet. Connect the antenna to the Antenna
terminal on the back of the unit.
POWER CONNECTION
The SIMBA SSB is constructed to be used in vehicles using either negative or positive ground. The red power lead is to be connected
to the positive terminal of the battery. The black lead is the Negative Lead. If the existing wiring is used be sure that it is heavy enough
to prevent voltage drop to the radio. A good source of battery voltage is at the accessory connection on the ignition switch. Using this
as a power source insures the radio will be off when the ignition switch is in the off position and power with be supplied to the radio
when it is in the on or accessory position.
