■Loading the Batteries Load three AA batteries in the battery
case in the "+" and "-" orientation
marked at the bottom of the case.
Caution!
· Do not use NiCad AA batteries on the market.
· Use new batteries of the same type and brand.
· Use high capacity of alkaline batteries.
■The NiMH Battery Pack
Caution!
· The battery pack is not charged when shipped.
It must be charged before use.
· It takes 10 hours maximum to fully charge the
battery pack with the EDC-105.
· Charging should be conducted in a temperature range of 0 to 40°C. (32 to
104°F)
· Do not modify, dismantle, incinerate or immerse the battery pack in the
water as this can be dangerous.
· Never short-circuit the battery pack terminals, as this can cause damage
to the equipment or lead to heating of the battery which may cause burns.
· Unnecessary prolonged charging (overcharging) can deteriorate battery
performance.
· The battery pack should be stored in dry place where temperature is from
-20 to +45°C. (-4 to +113°F)
Temperatures outside this range can cause the battery liquid to leak.
Exposure to prolonged high humidity can cause corrosion of metal
components.
· Normally, the battery pack can be charged up to 500 times. However, the
battery pack can be considered dead if the period of use drops off
markedly despite the pack being charged for the aforementioned charging
time. When this happens, a new pack should be used.
· Do not dispose the battery pack due to environmental protection. At the
end of its useful life, check with your local solid waste officials for details
on recycling options or proper disposal in your area. You may also
contact to our office.

■Prevent Short Circuiting the Battery Pack
Be extra cautious when carrying the
battery pack; short-circuiting will
produce surge current possibly
resulting in fire.
Terminals
DON'T carry with
metals of any type,
e.g. chains.
Do enclose inside a non-conductive enclosure.
(bags or handkerchief made only of non-
conductive material)
DON'T carry the
NiMH battery pack
inside bags of metal
plated interior.
Do protect by
spreading a non-
conductive sheet to
place on a flat surface.
DON'T place in the
proximity of metals or
conductives, e.g. nails,
chains.

■Battery Recharger
· Recharging with the EDC-105 1. Mount NiMH battery pack on the
transceiver. (The NiMH battery
pack itself is also mountable on
the battery recharger.)
2. Connect AC adapter plug to the
battery recharger.
3. Select the position 1 to 3 with the
lever on the recharger and adjust
the battery pack to fit with it.
(According to a type of battery
pack, position of the lever
changes.)
4.Set the battery pack to the
recharger making contact with
terminals on the rear side of the
transceiver and those on the
recharger side.
5. Connect the power plug to the AC
outlet.
6. The red light on the recharger
goes on and starts to recharge.
(While connecting to the AC outlet,
the charge status is maintained.)
Caution!
· When battery temperature exceeds a certain level, protective function
operates automatically and turns off the charge status. (The red light goes
off.)
In that case, unplug the recharger and dismount the transceiver or the
battery pack immediately. After removing the cause, then use the battery
recharger.
· Turn the transceiver power off before recharging the battery pack.
· Disconnect the EDC-105 from the outlet while not using it.
· Never charge battery packs of other manufactures with this charger.
· The required recharging time depends on the condition and model of a
battery pack, but it may take at most 10 hours. Refer to the instruction
manual of the battery pack.
· Never short-circuit the recharging terminals of this recharger with metal
objects, etc. The charger can be damaged.
· The ECD-105 does not work when the voltage from the wall outlet is
extremely low.

Adjusting the Squelch
The squelch silences the DJ-X3 except for signals above a certain level.
Squelch eliminates noise when the DJ-X3 receives less than a certain level.
"To unmute the squelch" means that the DJ-X3 receives a signal and
reproduces the sound.
Conversely, "to close the squelch" means that the DJ-X3 does not generate
audio because of insufficient signal level.
■Adjusting the Squelch Level
You can specify the signal level at which the DJ-X3 unmutes by adjusting the
squelch level.
1Press the [VOL/SQL (SET)] key (dial) twice.
(When "voL" is on the display, press it once.)
"SqL" will appear on the display.
2Adjust the squelch level by rotating the dial.
There are 11 squelch levels. (0-10) A higher squelch level requires a
stronger signal to unmute the squelch.
3Press the [FUNC/ENTER] key.
Be back to normal mode.
Tip
To keep the squelch open, set the squelch level to 0.

Basic Operation
■Monitor Function
The Monitor function temporarily unmutes the squelch. This is useful when the
desired signal is weak or intermittent. This function is activated when the status
of the [MONI(ST/SK)] key is set as Monitor function in the Set mode. For more
information, see "Setting Operation of the MONI key." (P.46)
There are two options in the Monitor function: PUSH and HOLD. Both two
options open squelch, and "B" appears on the display when press the
[MONI(ST/SK)] key.
· PUSH: Squelch unmutes while holding the [MONI(ST/SK)] key down. When
release the key, squelch goes back to be normal as you set before.
· HOLD: Squelch unmutes and remains the status once press the
[MONI(ST/SK)] key. Press the key again, then Monitor function is off,
and squelch goes back to be normal as you set before.
Switch the mode between PUSH and HOLD in the Set mode. For more
information, see "Setting Operation of the MONI key." (P.46)
■Mute Function
This function mutes sound. Even when squelch opens, this function makes
sound off, and while it is activated, beep sound does not go off either. This
function is activated when the status of the [MONI(ST/SK)] key is set as Mute
function in the Set mode. For more information, see "Setting Operation of the
MONI key." (P.46)
There are two options in the Mute function: PUSH and HOLD, as well. Both two
options execute Mute function, and "B" appears on the display when press the
