1 ABOUT LEAD FREE SOLDER (PbF: Pb free)
Note: In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that contains lead. We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn), Silver (Ag), and Copper (Cu). This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair work we suggest using the same type of solder although, with some precautions, standard Pb solder can also be used. Caution · PbF solder has a melting point that is 50°F ~ 70°F (30°C ~ 40°C) higher than Pb solder. Please use a soldering iron with temperature control and adjust it to 700°F ± 20°F (370°C ± 10°C). In case of using high temperature soldering iron, please be careful not to heat too long. · PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F (600°C). · If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible and be sure that any remaining is melted prior to applying the Pb solder. · When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the opposite side (See the figure below).
1.1.
Suggested PbF Solder
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper (Sn+Ag+Cu), you can also use Tin and Copper (Sn+Cu) or Tin, Zinc, and Bismuth (Sn+Zn+Bi). Please check the manufacturer's specific instructions for the melting points of their products and any precautions for using their product with other materials. The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

2 FOR SERVICE TECHNICIANS
ICs and LSIs are vulnerable to static electricity. When repairing, the following precautions will help prevent recurring malfunctions. 1. Cover the plastic parts boxes with aluminum foil and ground them. 2. Ground the soldering irons. 3. Use a conductive mat on the worktable. 4. Do not touch IC or LSI pins with bare fingers.
3 CAUTION
1. Danger of explosion if battery is incorrectly replaced. 2. Replace only with the same or equivalent type recommended by the manufacturer. 3. Dispose of used batteries according to the manufacture's Instructions.

Registering a Handset to a Base Unit
To Register an Additional Handset to a Base Unit (Easy Registration) The included handset and base unit are preregistered. After purchasing an additional handset, register it to the base unit. for few seconds to turn the handset on. Ensure that the additional handset is switched on. If it is not on, press and hold
Note: · If an error tone sounds, or if is still flashing, register the handset manually (manual registration). to stop. Start again from step 1. · If all registered handsets start ringing in step 2, press
· Charge the batteries of your additional handset for about 7 hours before initial use. · This registration method cannot be used for handsets that have already been registered to a base unit. Register the handset manually (manual registration). To Register a Handset to an Additional Base Unit (Manual Registration) You can register a handset to a base unit manually using the following method.
8.5.1.
Cancelling a Handset
A maximum of 6 handsets can be registered to a base unit. A handset can cancel its own registration (or the registration of another handset) that is stored in the base unit. This will allow the base unit to "forget" the handset.

Procedure
15.2. Troubleshooting for Speakerphone
When the customer's telephone line corresponds to the following conditions, and the transmission signal of SP-Phone is interrupted, performing the next set up to a cordless handset will improve it to some extent. Conditions 1. When customer's line has less line loss. ex.) The customer is using optical fiber, ISDN terminal adaptor, or PBX. In this case, receiving signal is strong and it may affect transmission signal. 2. When the other party is talking from noisy place. ex.) The other party is using cellular phone. The background noise is very loud. In this case, the noise from the other party (i.e. surrounding noise) may affect transmission signal. Setting Method · Change the address of EEPROM (0×0144) from 0×00 to 0×01.

21.3. Telephone Line Interface
· Bell signal detection · Clip signal detection · ON/OFF hook circuit · Audio circuits · DTMF tone signal circuits Bell & Clip (: Calling Line Identification Presentation: Caller ID) signal detection: In the standby mode, Q4 is open to cut the DC loop current and decrease the ring load. When ring voltage appears at the TP2 (A) and TP3 (B) leads (when the telephone rings), the AC ring voltage is transferred as follows; · A C13 R17 R24 IC8 Pin 60 (CID INp) · B C12 R16 R32 IC8 Pin 52 (CID INn) ON/OFF hook circuit: In the standby mode, Q4 is open, and connected as to cut the DC loop current and to cut the voice signal. The unit is consequently in an off-hook condition. When IC2 detects a ring signal or press the TALK Key onto the handset, Q5 turns on and then Q4 turns on, thus providing an off
