Manual Sleep
BLUELINE
is designed to go to sleep automatically after approximately 20 minutes of inactivity
to conserve the battery, although it can also be put to sleep manually by pressing and holding
both buttons [1] and [3] for 5 seconds. At the end of the 5 second period, a high to low beep is
emitted, the Bluetooth connection is disabled and the unit goes into a low power mode where the
battery will last many weeks.
It may be woken up by pressing any button or external switch. Optionally it may also be awoken
by joystick movement- see Configuring Joystick Wakeup section (above) for more details.
Configuring Joystick Wakeup
BLUELINE
is designed to go to sleep automatically after approximately 20 minutes of inactivity
to conserve the battery and can also be put to sleep manually (see next section), which is
especially useful if you are going to be transporting it. Once asleep, the unit monitors for new
activity and automatically wakes up so that you can carry on working. The Bluetooth connection
is lost while asleep although re-connection is both automatic and quick- usually a matter of
about 5 seconds.
By default, only button and external switch activity will wake up the unit. However, it is possible
to program the unit to also wake up on joystick movement. This may be beneficial for some users
as any activity can then wake the unit. On the other hand, it may be a disadvantage to therapists
who frequently transport the unit since it could result in the unit waking due to joystick
movement while in transit.
If you set
BLUELINE
to wake up on joystick movement as well as button/switch activity, it will
consume more power when asleep and will require charging more frequently.
To change the Joystick Wakeup setting, follow these steps:
1. Press the button marked Select [8] repeatedly until ‘8’ appears on the display [10].
After a short period the unit beeps and the display shows the current setting
without making any changes.
2. If you would like to change the setting, press the Modify button [9] repeatedly until
you see the required letter – either ‘A’ for Off (wakeup on buttons/switches only)
or ‘B’ for On (wakeup on buttons, switches and joystick movement). Table 2 also
shows these settings.
3. Once any changes have been made, allow the display to clear and they will be saved
in non-volatile memory so they will be retained even if you move BLUELINE to
another device or the battery becomes flat.
Note that even when the buzzer is disabled, it is still used occasionally to help with making
changes to the settings and to inform the user when the unit is being manually powered off.
In addition, a Dwell Click always results in a beep.
