Replace the Clock Battery - SM5

Core Product
SM5
Accessory

If the SM5's internal clock resets to January 1st, 2000 when you replace the primary batteries, you should replace the recorder's backup clock battery.

Before you begin

You will need a new, CR2032 lithium battery.

About this task


With the SM5 lying open, with the battery compartment on the right, the clock battery is installed at the top-center of the left panel of the recorder, to the right of the power switch. The battery slides in from the upper edge of the recorder, but a cutout in the plastic allows you to see a small part of the battery through the interior panel.

When the SM5 has no batteries installed and no external power source connected, a coin-shaped CR2032 battery keeps the internal clock running. This battery will generally last several years depending on how much time the SM5 spends active and powered. More time spent in storage, without batteries installed, will drain the clock battery more quickly than time spent deployed.

When the clock battery dies, the SM5's internal clock will reset to midnight on January 1st, 2000 when you remove the primary power source. In this state, you can still use the SM5 as long as you update the clock each time you install new batteries or reconnect an external power source. After you set the clock, it will run as normal until the primary batteries or external power source dies.

Procedure

  1. Turn off the SM5.
  2. Remove the battery bracket from the battery tray or the storage compartment along the side of the battery tray.

    The battery bracket is a long piece of plastic contoured to fit against 18650 batteries.
  3. Important: Do not use metal tools to remove the clock battery. Metal tools may damage the electronic components near the battery.
    Use the hooked end of the battery bracket to push the CR2032 clock battery out of its slot.

    A slot at the top of the inner face of the recorder allows the battery bracket to reach the clock battery.
  4. If the new CR2032 battery has a plastic packaging film, remove the film.
  5. Insert the new battery with the positive side of the battery facing towards you.
    The positive side of the battery is typically marked with a + symbol.

  6. Gently push the battery fully into place using one end of the battery bracket.


    When fully inserted, the battery is not visible beyond the edge of the recorder's inner panel.

  7. Turn on the SM5 and update its date and time settings.
