ET-410 DUoFONE Cordless Electronic Telephone System (430-0551) Installation Faxback Doc. # 17582 INSTALLING THE BASE UNIT The ET-410 comes with a modular plug installed on the end of its telephone cable. Connect it directly to the phone lines through a standard modular jack (used throughout the USA). 1. Disconnect the regular telephone from the wall jack and connect the ET-410 modular plug in its place. 2. Connect the AC power cord to a standard AC outlet. 3. If the ET-410's intercom feature will be used, plug a regular telephone into the modular jack on the back of the ET-410 Base Unit. A telephone connected here may be used normally or as an intercom with the ET-410 Handset. WARNING: This unit must be grounded for proper lightning protection. Installation Hints To avoid tripping over wires and damaging the unit, position the Base so that the wires are not in the way of normal activities. Fully extend the Base Unit antenna. Check to see that the POWER indicator is on. 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 24 -48 hours. To charge the Handset battery pack, the Base Unit must be installed as described above. 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 back 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 no one is talking on the ET-410. 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. It is acceptable to leave the Handset turned on while it's charging on the Base (after the initial 24 - 48 hour charge). However, to obtain maximum use of batteries, turn the Handset off to charge every month or so. Note however the Handset is disconnected from the line: it won't ring even if an outside call is received. (The regular telephone connected to the ET-410 will ring.) When the Handset is constantly charging, when battery power is used it 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 out of batter power, every month or so charge the Handset completely, than take it off the charging unit. Now use battery power alone unit it's almost discharged. Before all power is used, recharge the batteries completely. SETTING THE MODE (Tone/Pulse Dialing) To determine the proper setting for the TONE/PULSE switch, find out if the phone line is a rotary or 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 keys on the unit. If the dial tone continues, the line is a rotary type; if it stops, it is a true tone dialing line. If the line is rotary service, set the switch on the Base to PULSE. IMPORTANT: If a regular tone dialing phone system is familiar, don't be alarmed when the same tone sounds every time a key is pressed even if the switch on the Base Unit is set to TONE. The keytone on the Handset is there to assure that the key input is accepted. The tones for dialing are generated in the Base Unit. It is possible to communicate with the tone access equipment (bank-by- phone, alternate long distance service, etc.) even if the phone line is a rotary pulse type. After reaching the desired number (using the pulse dialing), press the LDT key. The LDT indicator will light and the ET-410 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 the unit to pulse mode, but it is actually not necessary because hanging up automatically returns the ET-410 to pulse mode. ENTERING THE SECURITY CODE Understanding the Security Code The exclusive programmable security code feature built into the ET-410 will prevent unauthorized use of the phone line. Each time the TALK PUSH HANG- UP button is pressed, a personally selected security code is automatically transmitted from the Handset to the Base Unit. The Basue Unit compares the code from the Handset with 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 the TALK PUSH HANG-UP button is pressed. To Enter the Code 1. With Handset POWER turned on, press the CODE ENTER button on the back of the Base Unit. The Handset will give a short tone and its TALK indicator will light. 2. Enter any four-digit number on the Handset keypad. (Use the 0 - 9 keys 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 unplugging the Base Unit. 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 hours. If the code is lost, there will be an error signal 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 a conversation or causing interference on the ET-410; this can happen with any cordless telephone.
