Page 11: Comparing The Song Meter Mini Bat And Song Meter Mini Bat 2
2.2. COMPARING THE SONG METER MINI BAT AND SONG METER MINI BAT The Song Meter Mini Bat 2 builds on the first-generation Song Meter Mini Bat by taking into account the feedback we have received from users running all types of deployments since the original product's launch in 2020.
Page 12 While the first-generation Song Meter Mini Bat's enclosure was comprised of a separate base and lid, the enclosure of the Song Meter Mini Bat 2 is joined by a permanent hinge, and the new, lockable latch can be more easily operated with one hand. The latch can be locked close using an appropriately sized padlock, without requiring an additional security bracket.
Page 13 The back of the Song Meter Mini Bat 2 features a tripod- style, ¼”-20 threaded mounting point. This enables you to mount the recorder using many accessories designed for trail cameras and similar devices.
Page 14 Song Meter Mini Bat. AA Batteries The Song Meter Mini Bat 2 AA can be used with either four or eight AA batteries. With eight AA batteries installed, you can record for twice as long as the original Song Meter Mini Bat could with AA batteries.
Page 15 Lithium-Ion Batteries The Song Meter Mini Bat 2 Li-ion can be used with any number of 18650 batteries between one and six. Unlike the first-generation Song Meter Mini Bat's Lithium-ion Lid accessory, 18650 batteries do not need to be installed...

Page 19: Hardware Overview
Song Meter Mini Bat 2 User Guide 3. HARDWARE OVERVIEW 3.1. EXTERNAL FEATURES Durable, Weather-Proof Enclosure The Song Meter Mini Bat 2 recorder is designed for long-term, outdoor deployment. Made from durable polycarbonate plastic, it is UV-resistant and weatherproof. The enclosure meets IP67 standards, meaning it can withstand temporary submersion in water up to a depth of one meter without leaking.

One of two Mounting Loops, which can accommodate bungee cords, rope, or cable locks up to a diameter of 0.420 in.
Page 22 Song Meter Mini Bat 2 User Guide The Barcode Label lists the recorder's Model Name and Serial Number. This information is also visible in the Song Meter Configurator app on the Status Screen (page 195). A waterproof Humidity Vent regulates humidity and pressure inside the enclosure.
Page 23 Song Meter Mini Bat 2 User Guide Versatile Mounting Options The enclosure of the Song Meter Mini Bat 2 is equipped with attachment points that support a wide range of mounting options: • Mounting Tabs at the top and bottom of the enclosure's back feature holes suitable for bolts or screws up to 3/16 in.
Page 24 Take extra care when attaching the recorder to young trees. The tree's growth over the course of a deployment could increase the strain on the enclosure. Lock Compatibility The enclosure of the Song Meter Mini Bat 2 is designed to support two layers of security:...
Page 25 Cable Lock Compatibility A cable lock can be threaded through the two Mounting Loops along the top of the Song Meter Mini Bat 2 to keep it attached to a tree or structure. The diameter of a cable lock must be narrower than 0.420 in.
Page 26 Support (page 284) to arrange a repair. Optional Acoustic Microphone Port The Song Meter Mini Bat 2 has a port for an optional, acoustic microphone. When installed, this allows the recorder to alternate between recording ultrasound and recording audio in the range of human hearing.

Page 30 Song Meter Mini Bat 2 User Guide The AA battery compartment holds two plastic battery trays. Each tray holds four AA batteries, and you can power the recorder with four or eight AA batteries in total. If you use only four AA batteries, all four must be installed in the same tray.
Page 31 Song Meter Mini Bat 2 User Guide For information on the different types of AA batteries, including Energizer® Ultimate Lithium™, see Types of AA Batteries (page 293). BEST PRACTICES FOR AA BATTERIES • Do not mix new or freshly charged batteries with used or uncharged batteries.
Page 32 Song Meter Mini Bat 2 User Guide Lithium-Ion Battery Compartment The lid of the Li-ion version of the Song Meter Mini Bat 2 holds between one and six lithium-ion 18650 batteries. You can install any number of 18650 batteries in any of the slots, and the recorder will work as intended, but using more batteries provides longer run time.
Page 33 Song Meter Mini Bat 2 User Guide BEST PRACTICES FOR LITHIUM- ION BATTERIES • Do not mix freshly charged batteries with drained batteries. • Unlike many rechargeable AA batteries, lithium-ion batteries are shipped with no stored charge. You must charge them before initial use.

Page 133 Schedules and Schedule Blocks A schedule for the Song Meter Mini Bat 2 can be made up of up to ten schedule blocks. If a schedule block were just a single recording period, having only ten would be severely limiting.
Page 134 Song Meter Mini Bat 2 User Guide Luckily, this type of schedule can be programmed with just one schedule block: Example: Record Five Minutes Every Hour For accessibility and ease of reading on multiple screen sizes, further examples will only present schedules as plain text.
Page 135 Duty Off: 00:55 END TIME: Time 00:00 With five simple commands, this one schedule block has told the Song Meter Mini Bat 2 to record five minutes at the start of each hour. The following sections expand on how each component works.
Page 136 Song Meter Mini Bat 2 User Guide The START TIME and END TIME commands are best understood in relation to each other. Everything the schedule block does occurs after the START TIME and continues until it reaches the END TIME. This is the case even when the START TIME and END TIME share the same value, as they do here.
Page 137 Song Meter Mini Bat 2 User Guide NOTE When you start your deployment for the first time, the Song Meter Mini Bat 2 will pick up in the middle of any schedule block that should be occurring at that time. The recorder does not need to wait for the next occurrence of the START TIME when it turns on.

Page 139 Song Meter Mini Bat 2 User Guide This means that, if your goal is to record the dawn chorus each day, the Song Meter Mini Bat 2 can time its recording period to follow sunrise as it shifts earlier and later in the day over the span of weeks and months.
Page 140 Song Meter Mini Bat 2 User Guide START TIME: Set - 01:30 Set means the START TIME is defined relative to the time of sunset on a given day. The negative sign, -, means the block starts earlier than sunset, and the offset, 01:30, means it starts 1 hour and 30 minutes prior to sunset.

Song Meter Mini Bat 2 User Guide 5.6. DEPLOYMENT LENGTH ESTIMATIONS The Song Meter Configurator app can estimate the expected run time it will take the Song Meter Mini Bat 2 to run out of battery power or SD card space. There are multiple factors that can affect battery life, so these estimations should be treated as approximate.

Page 155 Song Meter Mini Bat 2 is assumed to be recording nearby bats. For example, if you have the Song Meter Mini Bat 2 scheduled to run triggered, ultrasonic recording for 10 hours each night on a bat flyway, there may be significant periods of silence in between passing bats.

Factors Affecting SD Card Estimations When you select a preset SD card size in the Estimate battery and card life window, the estimation assumes that all of the card space is completely unused.
Page 157 Song Meter Mini Bat 2 User Guide at its default setting of 10%, the Song Meter Configurator app assumes that 10% of the length of each ultrasonic recording period is recorded to the SD card, and the remaining 90% of each period is unrecorded silence.
