MMB-33 Installation
(2) Position thè transceiver in thè bracket so that thè holes in
thè side panels are aligned with those in thè sides of thè
bracket, and bolt thè transceiver into piace with thè supplied
short screws and fiat washers.
Mobile Power Connection
Before connecting thè power cable thè maximum battery charging voltage
should be checked to ensure that it remains below 15V when thè engine
is run fast. If more than 15V, thè voltage regulator of thè car should
be adjusted before connecting thè transceiver.
Power connections should be made directly to thè automobile battery
using thè supplied cable with 10A in-line fuses. Connection to thè
cigarette lighter or other accessory circuii may cause thè fuse to
blow in that circuii. Connecting thè supplied DC power cable to thè
battery independently of thè rest of thè automobile electrical System
will minimize possible ignition noise pickup and excessive supply voltage
drop during transmission, while allowing operation with thè ignition off.
-10-
Do not connect any power to thè transceiver except via thè supplied
fused cable, and do not attempi to defeat or bypass thè fuses - they
are their to protect you and thè equipment.
Connect thè RED lead of thè power cable to thè POSITIVE (+) bat-
tery terminal, and thè BLACK lead to thè NEGATIVE (-) terminal. If
it is necessary to extend thè power cable, use #14 AWG or larger
insulated, stranded copper wire, and in ali cases use thè minimum
power cable length practicable to keep voltage drop minimal.
-WARNING-
NEVER APPLY AG POWER TO THE REAR PANEL POWER
JACK OF THE TRANSCEIVER. NEVER CONNECT DC VOLTAGE
OF MORE THAN 15 VOLTS TO THE POWER JACK. ALWAYS
REPLACE FUSES WITH 10A RATING. FAILURE TO OBSERVE
THESE PRECAUTIONS WILL VOID THE WARRANTY.
The SP-55 External Speaker is an optional accessory which allows thè
source of audio from thè transceiver to be repositioned for optimum
hearing. Especially practical for thè noisy mobile environment, thè
SP-55 includes its own swivel-type mounting bracket, and is available
from your Yaesu dealer. Also available to enhance safety and mobile
operating convenience are thè YH-1 Headset with miniature boom
microphone, and thè full size MF-1A3B boom microphone with flexible
arm (both of which use thè SB-10 PTT switch).
Base Station Installation
Mounting feet are supplied for thè transceiver when used as a base
station. A power supply capable of providing at least 6 A continuously
at 13.8VDC is required for operation from thè AC line, and an external
speaker is recommended. The FP-700 AC power supply is available
from your Yaesu dealer for this purpose. Use thè fused DC power
cable supplied with thè transceiver for making power connections, and
connect thè external speaker to thè EXT SP jack on thè rear panel.
