Cordless Telephone — P/N 730088/730087
The Aspire S System supports a Cordless Telephone. The DTR-4R-2 Cord-
less II (P/N 730088) is a 900 MHz spread-spectrum digital cordless tele-
phone that provides mobility, flexibility and convenience for those who
spend much of the workday away from their desk. Fully integrated with the
telephone system, the DTR-4R-2 Cordless II offers many standard features
such as Park, Do Not Disturb, Hotline, Voice Over and Voice Mail. Normally
paired with a companion keyset for improved 1-button call coverage capabil-
ities, the DTR-4R-2 Cordless II will also work as a stand-alone telephone.
Complemented by 4 fully programmable function keys (with LEDs), the
DTR-4R-2 Cordless II achieves a whole new level of convenience and
mobility. An easy-to-read LCD display, volume controls, a rechargeable
nickel-cadmium battery pack and a handy belt clip round out the elegant
and affordable DTR-4R-2 Cordless II Phone.
A second Cordless Phone is also available: the Cordless Lite II. The
Cordless Lite II offers the same features as the DTR-4R-2 Cordless II
except that it uses a NiMH battery and has FM modulation (single chan-
nel) instead of the spread spectrum modulation.
Recommended Usage Guidelines for Cordless Phones
In ideal conditions, multiple spread spectrum type cordless phones
(Cordless II can be utilized in the same environment. However, due to the
possible interference problems caused by the bases being placed in close
proximity to each other, we recommend the following:
Spr
ead Spectrum Phones (Cordless II P /N 730088)
Where users require greater range on the cordless phones and 3 or less
cordless phones are being used at a specific site, we recommend using
the spread spectrum cordless phone.
FM Modulation Phones (Cordless Lite II P /N 730087)
Where more than 3 cordless phones are to be used at one specific site, we recommend using the FM modula-
tion cordless phones which have 30-channel capability.
Note:
The range of the phones depends largely on the environmental factors, such as the building structure,
the size of the room, RF interference and other electronic equipment installed in the same area. For
optimum range and performance, we suggest the following:
1. Place the base units at least 15 feet apart. The performance of the phones become more stable
when the distance between the bases is greater.
2. Place the base unit in the center of the coverage area.
If the phone will also be used in an outdoor area, like a parking lot, install the base unit in an
area close to the window.
3. If a phone experiences interference and noise, press the channel key to select another channel.
