In the event some one that has requested this info and have not received it I am posting the info I received from Kenwood Tech service on the battery alignment of the TK-2170 etc portables.

Battery Detection Alignment & Check Procedures
This information will help you align and test the battery detection circuit in the TK-2170,
TK-3170 and TK-3173. Although the procedure can be done via the Test Mode in the
KPG-101D this document will give you step by step instructions for aligning the Battery
Detection via the front panel.
Required Test Equipment
Variable DC Power Supply capable of 4 amps or higher
Kenwood Battery Jig (Part Number W05-0909-00)
Digital Volt Meter DVM
50 ohm RF Dummy Load
Connections
1) Adjust the Variable DC Power Supply to 7.5 vdc
2) Attach the variable DC Power Supply to the Battery Jig and attach the Battery
Jig to the Radio
3) Attach DVM test leads directly to the Battery Terminals of the Battery Jig
4) Attach the 50 ohm RF Dummy Load to the antenna terminal of the radio
Radio data file configuration
1) Enable Panel Test and Panel Tuning Mode in radios data file
a. Panel Test and Panel Tuning can be found in the programming software
under
Edit > Optional Features > Common Page 2 > Mode
Panel Tuning Mode Alignment Procedures
1) Turn the Radio Off
2) Press and Hold the [A] Key while turning the Radio On
a. The radio will display frequency band (ex [UHF F1]) then [1-1]
3) Release the [A] Key
4) Press the [A] Key again to set the radio to LOW Power (L will illuminate on the
top right hand side of the display)
5) Press the [S] key to enter tuning item mode
6) Press the [C] Key seventeen times to toggle thru the various panel tuning
items until you reach [BATT XXX]
7) Place the radio into Transmit by pressing PTT
While the radio is Transmitting, Lower the DC Voltage on the Power Supply
to 5.9 vdc (Notice that while the DC voltage is lowered the reference number will be
lowered at the same time)
9) Once the power supply voltage has been lowered to 5.9 vdc Press the
Key
on the Radio to Store the New Reference Value then Release PTT
10) The Battery Detection Alignment is now Complete. Turn the Radio Off then
back On
Battery Level Check Procedures
It is recommended that the Battery Level Check be done on a conventional/Trunking
(user mode) frequency that has been set to low power instead of the Tuning Mode. While
checking the battery level it is recommended that the Battery Warning be set to “While
Transmitting” and the Battery Status be in the Off setting under Edit > Optional Features
> Common Page 2.
1) Adjust the variable power supply to 7.5 vdc
2) Select the channel that has been programmed to low power
3) Key the radio by pressing PTT
4) Lower the voltage on the variable power to supply to 6.8 vdc and confirm that the
radio TX LED is not flashing
5) Continue to lower the voltage on the power supply to 6.5 vdc. The radio TX LED
should begin to blink. This is the first indication to the end user that the radio
battery pack needs to be changed.
6) Continue to lower the voltage on the power supply to 6.2 vdc. The TX LED will
continue to blink and you will hear a tone indicating that the battery is now
exhausted. The radio will stop transmitting.
Programmable Battery Level Indication Options
The 170 and 173 Series radios can be programmed to different Battery Level Indications.
Below are the options and the indications that the end user will see at different voltages.
These indications should be given to the end user in addition to the instruction manual to
familiarize him/her of when the battery should be charged.
