SECTION 1. INTRODUCTION

The DX200 provides private, secure communication. E a ch base station can have up to fifteen Beltpacs
“registered” to it. Four of the fifteen Beltpacs can transmit at the same time. However, by connecting two or
more base stations together, these numbers can be increased. For example, two base stations can support thirty
Beltpacs, of which eig ht can transmit at the same time. Beltpacs c an b e use d either in the push-to- talk or hands­free mode. The base station operator can stop any Beltpac from transmitting.

®

The DX200 can be used w ith RTS
and 4-wire cabled intercoms can be operated at the same time. Also, using the AUX In and AUX Out
conn ections , a secon d 4-wir e int ercom ch annel can be used.

Either a monitor speaker or a local headset can be used with the DX200. Using a local headset, the base station
operator can talk to crew members on the cabled intercom channel, Beltpacs only or all channels.

The ba s e s tati on can be opera ted usi ng st andard DC electricity or a veh icle elect rica l system for mobile
operation. A power supply and cable are included with the base station.

BELTPAC SETUP AND REGISTRATION

The first time you operate the DX200 system, you must register each Beltpac for use with a specific base
station. The base station will then recognize all registered Beltpacs when their power is on, and will know the
diff erence betw een them and other electronic equipment operating on the same frequencies. If a Beltpac is added
or replaced later, the new one must be registered and the old one remains in memory. A maximum of 15
Beltpacs can be registered to a single base station at one time.

Set Up Beltpacs

Before registering them, set up all Beltpacs as follows.
Step 1. Insert a fully charged battery in the

Be ltp ac, with the metal contacts on
the end of the battery inse rte d first.
Press it in until it snaps.

Step 2. Place the Beltpac in the pouch.

Step 3. Plug the headset cable connector into the Beltpac.

NOTE: The a bove s e ttin gs are saved in memory and only need to be repeated when you want to change between

hands-free and PTT operation. When changing mode s , if bo t h power lights begin b linking, turn the B eltpac
off and beg in again.
Hands-f ree and Pus h-To -Talk mo de se ttings af f e ct b o th IC and ISO. Individual ad ju st ment is not po ss ib le .

• Push-To-Talk Mode Operation – press and hold the IC or ISO button for more than one second. In
PTT operation, audio will be transmitted only while you are pressing the IC or ISO button.

• Hands-free Mode Operation – Quickly press and release the IC or ISO button to “latch” the
transmitter on. Talk and listen, as in a normal telephone conversation. Press and release the IC or ISO
button aga in t o “u nla tch, ” to end th e conversa tion. All Beltpacs can be unlatched by the base station operator,
by pressing the UNLATCH button on the base station.

NOTE: In hands-free mode, pressing the IC button while latched in ISO will latch on IC. Pressing the ISO

button while latched in IC will latch on ISO.

Volume Up/Down

• Volume Up Adjustment – Each time you press and release the volume-up S button, a beep will be
heard in the earpiece as the volume increases one step. If you press and hold the volume-up button, repeating
beeps will be heard as the volume steps up to maximum. When maximum volume is reached, “maximum”
will be heard in the earpiece, and will be repeated until you release the volume-up button.

• Volume Down Adjustment – Each time you press and release the volume-down T button, a beep will
be heard in the ear piece as the volu me decreases one s t ep. If you pr es s and hold t he volum e- down butt on,
repeating beeps will be heard as the volume steps down to minimum. When minimum volume is reached,
rapidly repeating beeps will be heard.

Microphone Gain Adjustment

Some users talk louder or softer than others. To allow for this, microphone gain adjustment is provided.

To increase microphone gain – Press the volume-up S button while holding down the ISO button in
the normal operating mode. The microphone gain increas e can be monitored through sid etone, o r pre ferably by
someone else on a Beltpac or at the base station.

To Decrease microphone gain – Press the volu m e-down T button while holding down the ISO button
in the normal operating mo d e. The micropho ne g ain de crease can be mo nitored through side tone, or preferably
by someone els e on a Be ltp ac or at the base station.

NOTE: You will hear “Maximum” if you attempt to go higher than maximum microphone gain.

You will hear beeps if you attempt to go lower than minimum microphone gain.
Microphone gain will be saved in non-volatile memory and does not require readjustment each time
the power is turned on.

Change Batteries

When a bat tery becomes weak, a voice in th e
earpiece will say “Change battery.” When this
happens, take the Beltpac out of its pouch and
remove its battery. Slide the arrow-shaped battery­release latch in the direction of the arrow. Pull up
on the end of the battery near the battery-release
latch and lift the battery out of the Beltpac, or turn
the Beltp ac over and catch the batte ry in your hand.

When replacing a battery in the Beltpac, place the end
of the battery with the metal contacts into the battery
holder on the Beltpac, in the same position as the
battery you removed. Press the top of the battery
carefully into the battery holder until it snaps in place
under the battery-release latch.

SECTION 4. TROUBLESHOOTING

If you are unable to correct any of the problems described below, contact your dealer for assistance.

• Red light on base station power switch does not come on.

Be certain power cords are properly connected to base station, power supply and electrical outlet.

• Beltpac power lights do not turn green and “out of range” is heard in the headset.

Be certain your base station power is on. Turn the Beltpac and base station power on and off.
You may be too far from the base station. The range varies with each location’s layout.

• When trying to register, it keeps saying registration failed.

Refer to “If registration failed” on page 8, an d repeat the registrat ion procedure.

• Others cannot hear me when I talk.

Be certain the headset is securely connected to the Beltpac or base station, and that you are pressing the IC
or ISO button on the Beltpac, o r the TALK butto n on the base station. Be certain the appropriate IC or ISO
setting is selected under LOCAL HEADSET on the base station.

• People on the 4-wire intercom cannot hear me or I cannot hear them.

Be certa in t he cabl es are secu rely connected and the 4 - wire intercom is on. If us ing a local heads et, be
certain the IC setting is selected under LOCAL HEADSET on the base station.

• People on the RTS/ClearCom systems cannot hear me or I cannot hear them.

Be certa in t he cabl es are secu rely connected and the 2 - wire intercom is on. If us ing a local heads et, be
certain the IC setting is selected under LOCAL HEADSET on the base station.

• The 2-wire intercom is on and there is a loud squeal whenever I try to talk.

This can occur if two or more base stations are daisy-chained and the JP1 jumper on the circuit board in
one of the base stations has not been set properly. Contact your dealer.

• Settings are not retained when the base station power is turned off and on again.

The internal battery may be low. Contact your dealer.

2400MHz cordless telephone interference —
If there is a 2400MHz cordless telephone nearby, interference may occur. However, because the DX200
is a frequency-hopping system, this problem is unlikely. If it does occur, changing frequencies on the
telepho ne may allev iate the prob le m. If not, mo v e the pho ne as f ar as prac tical f ro m the b ase statio n, o r use
another type phone.

In the event of an electrical power outage —
such as from a lightning storm or power generator failure, if you experience problems with your HME
equipment after the electricity comes on again, unplug the AC power supplies from their electrical outlets
and wait 15 seconds, then plug th em back in.
