BULLETIN # 807
MODEL: TR-2400
SUBJECT: OPTIONAL CHARGE INPUT PROTECTION
Some users may request addition of a series diode to the Charge Jack to
prevent inadvertent shorting of the battery pack if a voltmeter probe,
headphone jack, or other conductor accidentally shorts across the external
Charge Jack. This can be used only for the standard wall charger. The
optional fast chargers require battery voltage be available at the charge
jack as feedback to the charqer requlator.
Add a Si diode in series with the battery charge line, at the Charge Jack.
Observe battery polarity. Charging current will drop approximately 2 ma.
1. Si diode must be rated at least 200mA.
2. Install carefully-don't short the YELLOW B+ lead when reassembling.
