Proper place ment of the beltpack can be crit i cal. The an ten nas
should be in the open. Bending the an ten nas up and plac ing
the beltpack in a pocket, etc., will re duce sys tem dis tance.
It is sug gested that the unit be worn on the belt with both an --

Base Sta tion - Rear Panel
Lo ca tion
Lo cate the base sta tion with the front and rear of the unit ac --
ces si ble so that switches may be set and con nec tions made.
Place the transmit and re ceive an ten nas on the base sta tion.
Make sure the an tenna’s color band match the color dot near
each an tenna. See “An tenna In for ma tion” sec tion for more in --
for ma tion on choos ing a proper op er at ing lo ca tion.
Power Con nec tion
Plug the sup plied power cord into the unit. The base sta tion has
an IEC power re cep ta cle that ac cepts 100 – 240VAC, 50 – 60Hz.
The spe cific re cep ta cle type is an IEC 60320/C14. The cord it ac --
cepts is an IEC 60320/C13. These cords are com mon and avail --
able through many re tail hard ware/elec tronic stores if the cord is
lost.
Trans mit Switches
There are two switches lo cated on the lower left side of the rear
panel. The up per switch sets the trans mit power lev el to high or
nor mal. The lower switch turns the trans mit ter on or off.
Trans mit Power
Set the power level to nor mal if us ing the beltpacks at
close to me dium dis tances (<200 feet, 161m,
line-of-sight) from the base sta tion. Set the power level to
high if us ing the beltpacks at a dis tance (>200 feet, 161m,
line-of-sight) from the base sta tion.
On/Off
Set the trans mit ter switch to on for nor mal use. In the off
po si tion the base station transmitter is dis abled. Set ting
the switch to off will dis ables all the beltpacks from hear --
ing any one else or even their own sidetone.
