Page 7: Introduction
Introduction The Song Meter SM2M+ Marine Recorder is a submersible 16-bit digital recorder designed for short or long term deployments in fresh or salt water. Like the terrestrial SM2+ recorder, the SM2M+ features flexible scheduling, extremely low power consumption, 16-bit digital recording and ease of use in a cost effective and easy to use package. - Page 8 You may want to download and install the Kaleidoscope conversion software and the Song Meter Configuration Utility software from the “downloads” section of our website at www.wildlifeacoustics.com.

Page 9: Product Family Overview
Product Family Overview Housing Options and Electronics Two models are available: The Song Meter SM2M+ Submersible and the Song Meter SM2M+ Deep water. The only significant differences between the two units are depth rating and power capacity. Song Meter SM2M+ Submersible uses a thick-walled PVC housing rated to 150 meters. -
Page 10: Hydrophone Options
Hydrophone Options H H igh-SPL Standard Ultrasonic Low Noise Dual Configuration Top Cap The Standard Acoustic hydrophone is used to record whale songs, dolphin whistles, and/or ambient noise levels, from infrasonic into ultrasonic frequencies. With the Ultrasonic upgrade, additional circuitry and the Ultrasonic hydrophone increases the recording bandwidth of the system to allow recordings not only from ultrasonic dolphin and porpoise echolocation calls, but also ultrasonic anthropogenic sounds as... - Page 11 and air guns. When combined with any of the other hydrophones in a dual hydrophone configuration, the unit can record quiet or distant sounds from any source including marine life with one hydrophone, and at the same time accurately record and quantify very loud sounds from anthropogenic sources with the High-SPL.
- Page 12 The sensitivity of each hydrophone is calibrated to a .1 dB resolution by the hydrophone manufacture. This value will be on a tag attached to the hydrophone cable and is reported as the average value over the band from 200Hz to 1.6 kHz in 100Hz steps. From the frequency response below you can extrapolate sensitivity across the rest of the frequency range with some degree of accuracy, as they are quite consistent in response.

To discuss optimal settings for your particular deployment, please contact Wildlife Acoustics’ support team at support2013@wildifeacoustics.com For any single hydrophone configuration, the unit is shipped with both channels connected to the single hydrophone, so it is arbitrary which channel you select for recording. - Page 16 1.5V alkaline batteries, 1.2V NiMH batteries or 3V-3.3V lithium batteries. The recommended lithium batteries are model U10026 from Ultralife Batteries. These are non-rechargeable lithium manganese batteries. Please contact Wildlife Acoustics support for more information. A board containing protection diodes in two configurations must be configured for the appropriate cell voltage.

The following chart shows approximate recording longevity in days for a 100% and 50% duty cycle schedule. Since the recorder uses very little power while sleeping, longevity for lower duty cycles can be deduced by multiplying the shown values (25% would be double 50% for example). - Page 18 N N ote: SDXC cards must be formatted to a FAT32 file system to work with the SM2M+. They will not work “out of the box”. Please contact Wildlife Acoustics support for more information on how to reformat the cards.

Page 19: Sealing The Housing
Sealing the Housing Warning: The SM2M+ ships with no O-rings installed, with no O-rings the unit will not seal and is unsuitable for deployment at any depth. The housing is sealed using two O-rings on the top cap. This is a redundant system, only one O-ring is necessary to seal, but two are used to assure a seal if one should become compromised. -
Page 20: Installing Battery Board And Connecting
Next apply a thin layer of lubricant all the way around the smooth inner diameter of the housing where the O-rings will mate as shown in the area between the two arrows below. This area and the O-rings should be free of dust, hair and other debris. Installing Battery Board and Connecting The battery board simply slides into the housing. -

by pressing the “back” button. Recorded sounds or vocalizations can then be immediately verified on a computer. Once satisfied, make sure the internal/external jumper is set to internal and the unit is powered. Press the “wake/exit” button and watch for with an announcement of scheduled recording time if in the future or “preparing to record”... - Page 22 Now insert each of the four legs of the hydrophone cage into the four top cap holes. Cinch a cable tie around the entire assembly to prevent the cage from slipping out of the mounting holes. There are grooves in the side of each leg to hold the cable tie in place.
- Page 23 Note: The SM2M+ package includes 4 O-rings, 5 packs of desiccant and a tube of O-ring lubricant. Additional deployment supplies can be purchased from McMaster Carr (http://www.mcmaster.com/). O-rings are part number 9557K333for the Submersible model or 9557K335 for the Deep Water model. 5 pack of desiccant is part number 2189K18.

Page 24: Deployment
Deployment Depth Rating The SM2M+ Submersible’s PVC housing is conservatively rated to 500ft (150m). This figure assumes a ten-year deployment life. In pressure testing, failure did not start until the equivalent pressure of about 100ft (300m). Deployments deeper than 150m are possible but not covered under warranty and will decrease the housing’s effective deployment lifespan. - Page 25 ocean floor by playing an acoustic signal from the surface. In this case, it is generally necessary to use a subsea float to increase the visibility of the housing when it surfaces. Copyright © 2011-2013 SM2M+ User Manual...

Page 26: Retrieval And Shipside Refurbishment
Retrieval and Shipside Refurbishment Retrieval Regardless of method of retrieval, take care in getting the unit shipside not to damage the hydrophone. If planning on using hooks to snare the housing, it might be best to deploy with a ring of floating nylon line attached to the bottom eyebolt to give a hooking point. -

simply be removed and replaced. Also replacing the AA batteries to assure that the clock setting is maintained is recommended. Flash cards can either be swapped for new empty cards or, if time allows, inserted into a laptop, transferred and then erased. Resealing The O-rings should be removed and the top cap thoroughly cleaned, paying special attention to the O-ring area. -
Page 28: Storage And Transport
Storage and Transport The SM2M+ ships in a high quality case suitable for storage and shipment. The case has wheels on one end for ease of travel and two latches which can accept locks for security. An accessory compartment allows storage of the spanner wrenches, O-rings, lubricant desiccant and other needed supplies. -
