ET-400 DUoFONE Cordless Telephone System (430-0550B) Installation Faxback Doc. # 16896 INSTALLING THE BASE UNIT The ET-400 is supplied with a telephone cable that has a modular plug at each end. Route the cable through the convenient groove on the back of the phone and connect one end to the modular jack on the bottom of the base unit. Connect the other end to the phone lines at the standard modular jack. Connect the AC power cord to a source of AC power. To install on the Wall The ET-400 can be hung on a wall if desired. Use two screws with heads that will fit into the key-hole slots on the back of the unit. Drill suitable holes for inserting the screws. The two holes should be 3-15/16" (100mm) apart. Thread the screws into the mounting surface, letting the heads extend out from the wall about 5/32" (4mm). Route the cables into the convenient groove and hang the ET-400 on the screws. To Mount on Wall Plate The spacing between the two holes is the same spacing as on a standard modular wall phone plate If you use this phone plate, you can mount the ET-400 directly on the plate. Use a shorter telephone cable (also available at Radio Shack) instead of the one supplied. To hang the Handset onto the Base Unit, first pull down the lever below the switchhook on the Base Unit. This secures the Handset in place on the Base Unit. Installation Hints - To avoid tripping over wires and damaging the unit, position the base so that wires are not in the way of normal activities. - Fully extend the Base Unit antenna. CHARGING THE HANDSET The Handset has a built-in rechargeable battery pack. As supplied, this battery pack is usually fully discharged. Before use, the Handset battery pack should be charged for at least 48 hours. To charge the Handset battery pack, the Base Unit must be installed. Charging on Base Unit 1. Be sure the POWER switch on the Handset is off. 2. Place the Handset in its cradle on the Base Unit. 3. The red charging indicator will light on the Handset when the Handset is charging properly. NOTE: Charging will be hindered if the charging contacts become dirty or tarnished; clean them occasionally with a pencil eraser. Charging Hints - Once the battery pack has been fully charged, recharge the Handset about two hours for every one hour it is used. - The Handset uses a small amount of power, even when you are not talking on the ET-400. A full charge will last 24 hours with the POWER switch set to ON; the charge will last several days with the switch in the OFF position. It is best to have the Handset on charge, whenever possible. - The charging rate is automatically reduced as the batteries approach a full charge. They will not be harmed by leaving the Handset on charge. - You may leave the Handset turned on while it's charging on the Base (after the initial 24-48 hour charge). To obtain maximum use of batteries, turn the Handset off to charge every month or so. Note however that the Handset is disconnected from the line: it won't ring even if an outside call is received. - When the Handset is constantly charging, whatever battery power is used is continually replenished. Because only a small amount of battery power is used, the unit loses the capability to use the rest of its power. To get the most use of battery power, every month or so charge the Handset completely, then take it off the charging unit. Now battery power is usable until it's almost discharged. When the BATT LOW indicator lights, recharge the batteries completely. ENTERING THE SECURITY CODE Understanding the Security Code The exclusive programmable security code feature built into the ET-400 will prevent unauthorized use of the phone line. Each time the TALK PUSH HANG- UP is pressed, the personally selected security code is automatically transmitted from the Handset to the Base Unit. The Base Unit compares the code from the Handset with the its security code. If the two codes are the same, the call may proceed; if they are not the same, the Handset will sound an error signal and the TALK indicator will go off. Once the security code is entered, the above "verification" procedure takes place automatically each time TALK PUSH HANG-UP is pressed. To Enter the Code 1. With the Handset turned on, press the CODE ENTER button on the back of the Base Unit. There will be a short tone from the Handset and its TALK indicator will light. 2. Enter any four-digit number on the Handset keypad. (Use 0-9 buttons only.) The TALK indicator will go off and another short tone will sound. The security code has now been entered in the Handset and the Base Unit. Security Code Hints - A memory protection circuit in the Base Unit holds the memory for 2- 1/2 hours after the Base Unit is unplugged. The security code will be lost, and must be re-entered, if the Handset battery pack discharges completely or if the Base Unit is unplugged for over 2-1/2 hours. If the code is lost, the error signal will be heard when TALK PUSH HANG-UP is pressed. - The security code prevents other cordless telephones from initiating or answering a call on the phone line. It does not prevent other radio units on the same frequency from inadvertently hearing bits of conversation or from causing interference on the ET-400; this can happen with any cordless telephone. SETTING THE MODE (TONE/PULSE DIALING) To determine the proper setting for the TONE/PULSE switch, first find out if your phone line is a rotary or touch-tone dialing type. To do this, connect the phone, set the switch to TONE, lift the Handset from the Base Unit, or press the TALK PUSH HANG-UP button (to get a dial tone), and press any of the number buttons on the unit. If the dial tone continues, it is a rotary type line; if it stops, it is a true touch-tone dialing line. If rotary service is in place, set the switch on the Base to PULSE. IMPORTANT: If a regular touch-tone system is familiar, don't be alarmed when the same tone occurs each time a key is pressed even if the switch on the Base Unit is set to TONE. they keytone on the Handset is to assure that the key input is accepted. The tones for dialing are generated in the Base Unit. You can communicate with the tone access equipment (bank-by-phone, alternate long distance service, etc.) even if the line is a rotary type. After reaching the desired number (using the pulse dialing), press the LDT key. The LDT indicator will light and your ET-400 is temporarily put into tone mode. Then key in the desired information such as a personal ID (billing) code number, area code and number, etc. Pressing the LDT key again will return to the pulse mode, but it is actually not necessary because when you hang up, the ET-400 automatically returns to pulse mode.
