Memo To: PSB Mailing List (Direct/Indirect)

From: Motorola 2-WAY Dealer Product Services & Direct ProductT Services, Plantation

Subject: Visar MultiUnit Charger Field Modification

Kits/Models affected: Visar Multi-Unit Chargers NTN7621A, NTN7622A and NTN7623A

Cause/Background: The Visar "B Revision" radio housing has increased in thickness. Due to this change, the "B" revision radio, when used with a High or Ultra-High capacity battery (NTN7394, NTN7395, NTN7397 or NTN7398) will not fit in the older Multi Unit Chargers (NTN7621A, NTN7622A and NTN7623A). The above batteries can still be charged in the "A" version Multi Unit Charger without the radio attached. The medium capacity battery (NTN7396) will fit in old or current chargers with or without "B" revision radios attached.

Corrective Action: In order to accommodate the changes described above, the Multi Unit Charger kits were upgraded to a "B" revision (NTN7621B, NTN7622B and NTN7623B). In addition, to support current users, a field upgrade kit has been set up in America's Part's Division (APD) to provide a convenient means of converting existing Multi Unit Chargers from "A" kits to "B" kits. The field upgrade kit is RPX4746A. It contains a new pocket assembly and complete instructions on how to perform the field upgrade.

A notice in the form of a stuffer sheet will be sent out with each new B revision model radio. This sheet will include the information above and inform the user to contact his dealer or service shop for the free upgrade. The notice will also let the user know that he can continue to charge his batteries without the radio attached in the A revision Multi-Unit Charger until it is convenient to make the change.

Parts and $35 labor is authorizd by warranty for A revision Visar Multiunit chargers.
