Changing the PROM
New features can be added to upgrade a Hand-held Monitor by replacing its PROM as
described below.
Caution
To prevent possible damage to the Hand-held Monitor, this operation should be
performed in an area equipped with suitable electrostatic discharge protection.
1. If the HHM is connected to AC power, disconnect it.
2. Remove the HHM battery pack as described on the previous page.
3. On the front of the Hand-held Monitor, remove the two Phillips-head screws located
near the 7 and HOME keys.
4. Gently raise the keyboard up from the bottom to release the lip between the
keyboard and the display.
5. Once this lip is free, open the keyboard to the right, as illustrated below. It is not
necessary to remove the ribbon connector.
