5. HOW TO REPLACE FLAT PACKAGE IC
5.1. Preparation
- SOLDER
Sparkle Solder 115A-1, 115B-1 or Almit Solder KR-19,KR-19RMA
- Soldering iron
Recommended power consumption will be between 30 W to 40 W.
Temperature of Copper Rod 662 ± 50°F (350 ± 10°C)
(An expert may handle between 60 W to 40 W iron, but beginner might damage
foil by overheating.)
- Flux
HI115 Specific gravity 0.863
(Original flux will be replaced daily.)
5.2. Procedure
1. Temporary fix FLAT PACKAGE IC by soldering on two marked 2 pins.
*Most important matter is accurate setting of IC to the corresponding soldering
foil.
2. Apply flux for all pins of FLAT PACKAGE IC.

3. Solder employing specified solder to direction of arrow, as sliding the
soldering iron.
5.3. Modification Procedure of Bridge
1. Re-solder slightly on bridged portion.
2. Remove remained solder along pins employing soldering iron as shown in

9.4. Ringing
24 2005-05-13
After detecting the Ring signal from circuit, Base Unit sends a ring signal DATA
(Ring) on the base's (a) TX frequency, then the Handset starts ringing.
Note: (a) is channels 1-10 (old)...cthese channels are paired.
9.5. Ports for Transmitting and Receiving of Data
Handset: transmitting... 44 Pin receiving... 25 Pin
Base Unit: transmitting... 10 Pin receiving... 7 Pin
9.6. Waveform of DATA Used for Cordless Transmission and
Reception
The DATA which is transmitted from the Handset to the Base Unit is combination
of DATA 0, DATA 1, DATA Delimit, Pre data and End data of P1.
The DATA which is transmitted from the Base Unit to the Handset is combination
of DATA 0, DATA 1, DATA Delimit, Pre data and End data of P2.
