Electronics; Battery Backup - Medline ALTERRA 1385 Operation And Maintenance Manual

CAUTION
If all four casters are not locked, swivel and wheel rotation will allow bed motion with little
or no resistance. This can result in loss of balance, fall and personal injury. Ensure that all
four casters are locked to avoid any bed movement during resident transfer and/or use. The
central locking mechanism can be used for most situations where locking casters are needed.
However, movement near the head section of the bed may still result if force is applied. The
bed will be most secure if the head end casters are locked along with the central lock and/or
foot end casters.
