BKR0102 Update Work Instructions
Control Document
Applies to: This Instruction applies to BKR0102 Li-Ion batteries manufactured
between 2022 and January 2024.
Condition: BKR0102 Li-Ion batteries are reporting incorrect capacities
relative to the actual capacity of the battery.
Correction: Upgrade the battery characteristic file to rev 7. (Most batteries
are revision 5). The battery upgrade is accomplished by simply inserting a
battery into a BKR0303-2 DUC (Dual Unit Charger) that has been upgraded to
Firmware revision 3.0.16. See General Instructions below for more detail.
Requires: BKR0721 CFP (Charger Field Programmer) with FW 3.0.16 loaded.
General Instructions:
The BKR0102 Li-Ion battery was developed with a system that constantly
calibrates its capacity. The original characteristics file
(vSAM_Rev5_13052022.INI) had a flaw that calibrated the battery capacity
erroneously. The BKR0303-2 Dual Unit Charger communicates with the BKR0102 Li-
Ion battery and can determine the characteristic file programmed in the
battery. If a BKR0102 Li-Ion battery is inserted into a BKR0303-2 DUC that has
been upgraded to FW 3.0.16 and this BKR0102 battery does not contain the
corrected file (vSAM_Rev7_15022024.INI), the BKR0303-2 will upgrade the
characteristic file (once only) to the correct file automatically and then
continue to charge the battery as normal.
The BKR0303-2 DUC FW can be upgraded to FW 3.0.16 simply by inserting the
BKR0721 CFP with the 3.0.16FW preprogrammed in the CFP.
Using the BKR0721 CFP to program BKR0303-2 DUC
· BKR0721 CFP Usage Best Practices: · Dry Location Use ONLY · Indoor Use ONLY
· Recommend using ESD best practices (e.g. using an ESD Ground Strap) when
programming · Recommend NOT transmitting 20way radio in immediate proximity
while programming
· BKR0721 CFP requires 3-AAA Alkaline Batteries; Alkaline Batteries ONLY · DO
NOT use other chemistry batteries, e.g. Li-Ion, Zinc-chloride, or NiMH. ·
INSTALL in the correct orientation · Cell orientation is indicated on the Cell
Tray · Incorrectly installed battery will not power the CFP; the cell tray has
mechanical features that prevent reverse polarity to the CFP which could
otherwise damage the CFP
· Once the 3-AAA batteries are installed

Note, by the time it takes to add the 3rd battery, install the cover, and flip the unit over, you may only see 1-cycle of the Programming and Power Status LEDs going through Solid RED, Solid YELLOW, Solid GREEN
· Additional battery installation notes: o If the installed batteries are not new, e.g., if the resultant power is approx.. between 3.75 and 4V, once the BKR0721 CFP goes through its initialization sequence, then Power Status will show Solid Yellow This state indicates that the BKR0721 CFP is still usable, but has Low Power o If the installed batteries are not new, e.g., if the resultant power is approx. between 3.6 and 3.75V, once the BKR0721 CFP goes through its initialization sequence, then Power Status will show Solid Red This state indicates that the BKR0721 CFP is not usable, and batteries will need to be replaced The BKR0721 CFP LED will indicate Solid Red until BKR0721 CFP SW Shutdown threshold is met (~<3.6V), and then turn OFF o If the installed batteries are not new, e.g. if the resultant power is < 3.6V the BKR0721 CFP goes through its initialization sequence, then Power Status will “quickly” show Solid Yellow, Solid Red, and then OFF This state indicates that the BKR0721 CFP batteries are DEAD and need to be replaced o Approx. every 15-minutes, the BKR0721 CFP re-assesses Power Status, and provides a new indication (if necessary) o Once the Low Power Thresholds are met (either Solid Yellow and/or Solid Red), the BKR0721 CFP will maintain that indication(s) thru the remaining life of the product
· Programming o Target device/charger (BKR0303-2 DUC) that is being reprogrammed MUST be powered through its External PSU o The BKR0303-2 DUC is only reprogrammable via Pocket -0- or its Priority Pocket The DUC has an indication (insert molded symbol) designating the priority pocket · The Priority Pocket has a molded in ‘square” in the floor of the pocket; the Secondary Pocket has a ‘circle’ molded into the floor of the pocket

o Programming LED Indications once installed in a
Pocket: Solid Yellow indicates to the user the Portable Field Programmer is
programming the
charger Solid Green indicates charger/pocket has programmed successful
· IMPORTANT NOTE: Once the target device indicates that it has successfully
been
reprogrammed (Solid GREEN LED), it is imperative that the reprogrammed charger
is power cycled to complete/initiate the software update Solid Red indicates
charger/pocket programmed unsuccessful
Note, the Solid Green or Solid Red LED will be maintained until the Portable
Field
Programmer is removed from the charger to address the use case in which the
user
is distracted or leaves their station Additionally, if “programming” (Solid
Yellow) and the CFP is either removed or the charger
powers OFF, then the Programming LED will show Solid Red (transition from
Solid Yellow to
Solid Red) and maintain that indication until the CFP is reinserted into a
charger or the
charger is powered up again Note, programming takes less that 10-sec to
complete
· Battery Life o Even under heavy use, i.e., continuously programming a charger, we realized > 5-days of battery life, so light use should experience a long battery life However, for optimal product life, it is recommended that the CFP is NOT left in the Charger Pocket as the LED Indication (either Green or Red will be left ON) will tax the battery life Again, noting that the Solid Green or Solid Red LED will be maintained until the Portable Field Programmer is removed from the charger to address the use case in which the user is distracted or leaves their station
