Beep Sequences - Texas Instruments CBL 2 Reference Manual

Beep Sequences

The CBL 2 makes four kinds of sounds:
A low tone followed by a high tone (low-to-high beep).
A medium tone followed by another medium tone (medium-medium beep).
A high tone followed by another high tone (high-high beep).
A "tick" sound when a key is pressed.
The following bullets explain when beep sequences normally occur and what the beep
sequences mean.
When the CBL 2 completes initialization, you will hear the startup sequence: high-
high beep, medium-medium beep, low-to-high beep (6 total beeps, plus LEDs light
up in this order: red LED, yellow LED, and green LED)
When you press the QUICK SETUP button:
the medium-medium beep sounds if a sensor is attached to the CBL 2.
the high-high beep sounds if no sensors are attached to the CBL 2.
When the CBL 2 is connected to a calculator during sampling commands:
the medium-medium beep sounds when initializing data collection.
the medium-medium beep sounds when starting data collection (transition from
pre-store to store).
the medium-medium beep sounds when completing data collection.
Note: If the sampling timing causes the beeps to run together, the CBL 2 software may not
sound all the beeps.
Note 2: You will not get all the beeps when Fast Sampling is enabled.
Note 3: You will not get all the beeps when using triggering.
When you set the CBL 2 for manual trigger and press the START button, a medium-
medium beep sounds.
When you press the TRANSFER BUTTON:
the low-to-high beep sounds when the transfer succeeds.
the high-high beep sounds if the transfer fails for any reason.
When an overcurrent condition is detected, five high-high beeps sound. (This causes
an error, which causes even more beeps to sound.)
When the CBL 2 begins a full self-test, three low-to-high beeps sound.
When self-test completes:
the low-to-high beep sounds if self-test passes.
the high-high beep sounds if self-test fails.
