Select an area to install the Excursion 36270 where it is closest to the center of your home or office. This will improve the operating range of the unit. Keep the Excursion 36270 base unit away from electrical equipment. Radio Frequency Interference (RFI) is sometimes generated by these appliances, which can cause degradation in cordless reception. Keep the handset batteries charged as much as possible. Weak handset batteries can limit the range of cordless operation. MAXIMIZING BATTERY LIFE Repeated use or recharge of Ni-Cd batteries without periodic full discharge results in reduced useable charge time. When you notice the usable charge duration decreasing, fully discharge the Ni-Cd battery and recharge as described:
DISCHARGING 1. Unplug the telephone line cord from the Excursion 36270. 2. Make sure that the adapter is connected. 3. Lift the handset out of the base cradle. 4. Press the TALK button of the handset (IN USE LED indicator should light) and start discharging. Once the BATT LOW LED indicator starts flashing, it means that the battery level is low. Let it fully discharge for 12 hours. Once the Ni-Cd battery is fully discharged, you may now charge the battery to its full capacity. CHARGING 1. Make sure the adapter and telephone line cord are connected to the Excursion 36270. 2. Place the handset on the base cradle. The CHARGE LED indicator of the base unit will light steadily. charge. 3. Leave the handset charging on the base for 14 hours continuously to get a maximum 4. The Excursion 36270 is now ready for regular use.

There are certain difficulties in using radio frequencies with a cordless telephone. While these are normal, the following could affect the operation of your system. NOISE: Electric pulse noise is present in most homes at one time or another. This noise is most intense during electrical storms. Certain kinds of electric equipment such as light dimmers, fluorescent bulbs, motors, and fans also generate noise pulses. Because radio frequencies are susceptible to these noise pulses, you may occasionally hear them in your handset. Generally, they are minor annoyances and should not be interpreted as defects in your system. RANGE: Because radio frequencies are used, location of the base unit can affect operating range. Try several locations in your home or business and pick the one that gives you the clearest signal. INTERFERENCE: Some electronic devices operate in and/or generate interference near the operating frequencies of your cordless telephone. While several protection circuits are used to prevent unwanted signals, there may be periods when these unwanted signals cause interference. If interference occurs frequently, it can be minimized or eliminated by lowering the height of your base antenna or by relocating the base unit. You can check for interference before selecting the final base unit location by plugging in the phone.
