DSX Cordless Lite II Telephone Installation Tips
Important
• Only connect the cordless base unit to a DSX-80/160 16ESIU PCB port or a DSX-40 digital
station port. Do not plug the base into an analog port or a DS-2000 16DSTU PCB.
• For best results, the base unit should be placed in line-of-site with its handset.
• Cordless telephone range and reception can vary from site to site. Some of the things that
may adversely affect range and reception are:
- Placing the base against or close to a wall (particularly if the wall has metal studs).
- Positioning the base close to a device that emits Electromagnetic Interference (EMI),
such as a TV, radio, computer, fluorescent light, fax machine, or printer.
- Installing the base close to other 900 Mhz devices, such as Symbol or Telex hand-held
inventory devices.
- Installing the base above a ceiling that uses foil-backed insulation.
- Installing the base behind a door which can be closed, tinted windows, or one-way glass
which will separate the base from the handset.
• Always raise the base unit antenna to its full vertical position.
• When installing more than one cordless telephone in the same site:
- Be sure the base units are at least 15 feet apart.
- Do not install more than 12 cordless telephones in an area of close proximity.
- After installation, change each telephone’s channel by pressing CH on the handset. This will
minimize interference between your cordless telephones. There are 30 available channels.
• The handset must charge 5-8 hours in its charger prior to initial use.
• The Nickel Metal Hydride Rechargeable Battery Pack is recyclable. If you replace a battery
pack, always dispose of the old pack along with your other recyclable materials.

Installation
Installing the Base
Connecting the Base
To connect the base to the DSX system (Figure 2: Installing the Base) :
1. Install a modular jack within 6 feet of the base and within 6 feet of an available standard (NEMA 5-15R)
120 VAC outlet.
2. Run a single pair of 24 AWG station cable from an available 16ESIU PCB digital station port on a sta-
tion block to the modular jack.
3. Terminate the station cable WHT/BLU - BLU/WHT leads to the RED and GRN lugs on the modular jack.
4. Plug one end of a modular line cord into the base LINE IN jack; plug the other end of the line cord into
the modular jack.
5. (Optional) Plug an accompanying DSX keyset into the LINE OUT jack in the base.
- While the keyset and the cordless handset are idle, you can press Cordless and Desk on the base
to activate either phone (and deactivate the other).
To connect the AC Adaptor to the base:
1. Run the AC adaptor cord under the strain relief on the back of the base as shown.
2. Plug the AC adaptor into AC outlet.
3. Be sure the base antenna is in the vertical position.
Checking the Base LEDs
Normal Operation when the cordless handset is operational
❥
When the cordless handset is operational, the Power and Cordless LEDs are on.
❥
When the keyset is operational, the Power and Desk LEDs are on.
Troubleshooting
❥
If the Power LED is off, the base power supply is not properly connected.
Be sure to review Guidelines for Placing the Base, Figure 3: Correct Installation Methods, and Figure 4:
Incorrect Installation Methods prior to connecting the base unit to the system.
Guidelines for Placing the Base
1. For best results, the base unit should be placed in line-of-site with its handset.
2. Cordless telephone range and reception can vary from site to site. Some of the things that may
adversely affect range and reception are:
• Placing the base against or close to a wall (particularly if the wall has metal studs).
• Positioning the base close to a device that emits Electromagnetic Interference (EMI), such as a TV,
radio, computer, fluorescent light, fax machine, or printer.
• Installing the base close to other 900 Mhz devices, such as Symbol or Telex hand-held inventory
devices.
• Installing the base above a ceiling that uses foil-backed insulation.
• Installing the base behind a door which can be closed, tinted windows, or one-way glass which will
separate the base from the handset.
3. Always raise the base unit antenna to its full vertical position.
4. When installing more than one cordless in the same site:
• Be sure the base units are at least 15 feet apart.
5. After installation, change each telephone’s channel by pressing CH on the handset. This will minimize
interference between your cordless telephones.

Wall-Mounting the Base
Mounting the Base on the Wall
To mount the base on the wall (Figure 5: Mounting the Base on the Wall):
1. Run the base line cord in the wide wire channel as shown, but do not plug it into the base.
2. Run the AC adaptor cord in the narrow wire channel as shown, but do not plug it into the base.
3. Using suitable fasteners, attach the wall-mount bracket to the wall in the desired location.
