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.

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).

•

• Exercise care while using higher temperature soldering irons.: Do not heat the PCB for too long time in order to prevent

• •

solder splash or damage to the PCB.

•

• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F (600°C).

• •

•

• 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: 0.3 mm, 0.6 mm and

1.0 mm.

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.

IC3

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.

6.1. Warning When Constructing the Base Unit

CHG terminal is properly fit in the cabinet.

Rib

CHG terminal comes out of rib by pulling black lead wire when opening the cabinet and turning the PCB over. The terminal cannot have enough elastic force, cannot have good contact with handset, and it will result in charge problem.

9. Confirm hearing tone: 380mVrms ± 100mVrms.

10. Adjust audio level if required. (Make sure current value using “getspkrgain”. And then execute the command “setspkrgain xx”, where xx is the value.)

11. Confirm that the audio distortion at 600R of Tel-simulator is < 5%.

(P) Charging Check - 1. Connect Charge Contact 12Ω/2W resistor between charge+ and charge-.

2. Measure and confirm voltage across the resistor is 2.3V ± 0.2V.

Point

(Q)* Audio Check - 1. Link with Handset.

2. Set line voltage to 48V and line current to 40mA.

3. Input -45dBm/1kHz to MIC of Handset. Measure the Level at Line I/F and distortion level.

4. Confirm that the level is -7.5 ± 2dBm and that the distortion level is < 5% at TEL Line (600Ω Load).

5. Input -20dBm/1kHz to Line I/F. Measure the level at Receiver of Handset and distortion level (*Receive volume set to second position from minimum).

6. Confirm that the level is -23 ± 2dBm and that the distortion level is < 5% at Receiver (vol = Low, 150Ω Load).
