Locking of keyboard
To lock the keyboard, keep the “Mode” button (bottom button with an embossed cross
pattern) pressed, while simultaneously pressing the “Rec” button (top button with round
indent the size of a pinhead). By doing this, all functions of the device are disabled. This is
indicated by the message “Keyboard locked”. To unlock the keyboard, press the same
combination of buttons once again. The device will acknowledge this with the message
“Keyboard active”.
Attention: To conserve energy, the device will automatically go into sleep mode after ten
minutes of inactivity. The device will reactivate upon pressing of any of the five topside
buttons. Please note that this will not unlock the keyboard.

Memory and battery status check
To check the memory and battery status, press the “Mode” button (bottom button with an
embossed cross pattern) for at least 1.5 seconds. Then, you will hear a message indicating
the memory and battery status. Battery status is indicated in one of four levels, they are:
“Battery fully charged”, “Battery charged”, “Please charge battery” and “Charge battery
urgently”. Reaching the third level (“Please charge battery”) indicates that about 40% of
battery charge is still available. The memory status will tell you which memory and which
folder are currently active and which portion of the active memory is still available for
recording, e.g., “Memory card voice recorder, 3, 256 MB, 30% available”.
At stage four of the battery status (e.g., “Charge battery urgently”) recording is not allowed
anymore to protect the already recorded messages. Playback is still possible and the
recorded messages are safeguarded. Four very brief low pitched warning beeps sound
after each played back message to alert the user to recharge the battery. At stage four of
the battery status no user settings such as volume, pauses or similar commands are
retained upon going into sleep mode. This again ensures safeguarding of the already
recorded messages. If stage four of the battery status is reached during a recording, the
device will automatically terminate the recording and will announce the battery status. The
performed recording is saved correctly up to the point at which the battery status beeps
were heard.
The built-in rechargeable high capacity battery allows approximately 10 hours of use with
one full charge when recording through the internal microphone and playback over the
headphones. Actual power use varies with the exact use of the device. The least amount of
power is consumed during continuous recording through the internal microphone. The most
power is consumed for high volume playback over the built-in loudspeaker.

Battery charging
The built-in battery may be charged by connecting Milestone 311 to the powered battery
charger or by connection the device to a computer via the USB cable. The connection for
the battery charger is located on the right side of the face side pointing away from you. The
connection for the USB cable is located in the middle of the same side. Start of the
recharging cycle is acknowledged by a long “low-pitched” beep a few seconds after chrging
is initiated. During charging, the red signal lamp flashes about every three seconds. Please
check the power supplies if the “low-pitched” beep is not heard after connecting the cable.
